Description
The Qimonda 256-Mbit GDDR3 Graphics RAM is a high speed memory device, designed for high bandwidth intensive applications like PC graphics systems. The chip's 4 bank architecture is optimized for high speed. HYB18H256321BF uses a double data rate interface and a 4n-pre fetch architecture. The GDDR3 interface transfers two 32 bit wide data words per clock cycle to/from the I/O pins. Corresponding to the 4n-pre fetch a single write or read access consists of a 128 bit wide, one-clock-cycle data transfer at the internal memory core and four corresponding 32 bit wide, one-half-clockcycle data transfers at the I/O pins. Single-ended unidirectional Read and Write Data strobes are transmitted simultaneously with Read and Write data respectively in order to capture data properly at the receivers of both the Graphics SDRAM and the controller. Data strobes are organized per byte of the 32 bit wide interface. For read commands the RDQS are edge-aligned with data, and the WDQS are centeraligned with data for write commands. The HYB18H256321BF operates from a differential clock (CLK and CLK). Commands (addresses and control signals) are registered at every positive edge of CLK. Input data is registered on both edges of WDQS, and output data is referenced to both edges of RDQS. In this document references to "the positive edge of CLK" imply the crossing of the positive edge of CLK and the negative edge of CLK. Similarly, the "negative edge of CLK" refers to the crossing of the negative edge of CLK and the positive edge of CLK. References to RDQS are to be interpreted as any or all RDQS<3:0>. WDQS, DM and DQ should be interpreted in a similar fashion. Read and write accesses to the HYB18H256321BF are burst oriented. The burst length is fixed to 4 and 8 and the two least significant bits of the burst address are "Don't Care" and internally set to LOW. Accesses begin with the registration of an ACTIVATE command, which is then followed by a READ or WRITE command. The address bits registered coincident with the ACTIVATE command are used to select the bank and the row to be accessed. The address bits registered coincident with the READ or WRITE command are used to select the bank and the column location for the burst access. Each of the 4 banks consists of 4096 row locations and 512 column locations. An AUTO PRECHARGE function can be combined with READ and WRITE to provide a self-timed row precharge that is initiated at the end of the burst access. The pipe lined, multibank architecture of the HYB18H256321BF allows for concurrent operation, thereby providing high effective bandwidth by hiding row precharge and activation time. The "On Die Termination" interface (ODT) is optimized for high frequency digital data transfers and is internally controlled. The termination resistor value can be set using an external ZQ resistor or disabled through the Extended Mode Register. The output driver impedance can be set using the Extended Mode Register. It can either be set to ZQ / 6 (auto calibration) or to 35, 40 or 45 Ohms. Auto Refresh and Power Down with Self Refresh operations are supported. An industrial standard PG-TFBGA-136 package is used which enables ultra high speed data transfer rates and a simple upgrade path from former DDR Graphics SDRAM products.

Ball Definition and Description
TABLE 2
Ball Description
Ball CLK, CLK Type Input Detailed Function Clock: CLK and CLK are differential clock inputs. Address and command inputs are latched on the positive edge of CLK. Graphics SDRAM outputs (RDQS, DQs) are referenced to CLK. CLK and CLK are not internally terminated. Clock Enable: CKE HIGH activates and CKE LOW deactivates the internal clock and input buffers. Taking CKE LOW provides Power Down. If all banks are precharged, this mode is called Precharge Power Down and Self Refresh mode is entered if a Auto Refresh command is issued. If at least one bank is open, Active Power Down mode is entered and no Self Refresh is allowed. All input receivers except CLK, CLK and CKE are disabled during Power Down. In Self Refresh mode the clock receivers are disabled too. Self Refresh Exit is performed by setting CKE asynchronously HIGH. Exit of Power Down without Self Refresh is accomplished by setting CKE HIGH with a positive edge of CLK. The value of CKE is latched asynchronously by Reset during Power On to determine the value of the termination resistor of the address and command inputs. CKE is not allowed to go LOW during a RD, a WR or a snoop burst. Chip Select: CS enables the command decoder when low and disables it when high. When the command decoder is disabled, new commands with the exception of DTERDIS are ignored, but internal operations continue. CS is one of the four command balls. Command Inputs: Sampled at the positive edge of CLK, CAS, RAS, and WE define (together with CS) the command to be executed. Data Input/Output: The DQ signals form the 32 bit data bus. During READs the balls are outputs and during WRITEs they are inputs. Data is transferred at both edges of RDQS. Input Data Mask: The DM signals are input mask signals for WRITE data. Data is masked when DM is sampled HIGH with the WRITE data. DM is sampled on both edges of WDQS. DM0 is for DQ<0:7>, DM1 is for DQ<8:15>, DM2 is for DQ<16:23> and DM3 is for DQ<24:31>. Although DM balls are input-only, their loading is designed to match the DQ and WDQS balls. Read Data Strobes: RDQSx are unidirectional strobe signals. During READs the RDQSx are transmitted by the Graphics SDRAM and edge-aligned with data. RDQS have preamble and postamble requirements. RDQS0 is for DQ<0:7>, RDQS1 for DQ<8:15>, RDQS2 for DQ<16:23> and RDQS3 for DQ<24:31>. Write Data Strobes: WDQSx are unidirectional strobe signals. During WRITEs the WDQSx are generated by the controller and center aligned with data. WDQS have preamble and postamble requirements. WDQS0 is for DQ<0:7>, WDQS1 for DQ<8:15>, WDQS2 for DQ<16:23> and WDQS3 for DQ<24:31>. Bank Address Inputs: BA select to which internal bank an ACTIVATE, READ, WRITE or PRECHARGE command is being applied. BA are also used to distinguish between the MODE REGISTER SET and EXTENDED MODE REGISTER SET commands.

Ball A<0:11>
Type Input
Detailed Function Address Inputs: During ACTIVATE, A0-A11 defines the row address. For READ/WRITE, A2-A7 and A9 defines the column address, and A8 defines the auto precharge bit. If A8 is HIGH, the accessed bank is precharged after execution of the column access. If A8 is LOW, AUTO PRECHARGE is disabled and the bank remains active. Sampled with PRECHARGE, A8 determines whether one bank is precharged (selected by BA<0:1>, A8 LOW) or all 4 banks are precharged (A8 HIGH). During (EXTENDED) MODE REGISTER SET the address inputs define the register settings. A<0:11> are sampled with the positive edge of CLK. ODT Impedance Reference: The ZQ ball is used to control the ODT impedance. Reset pin: The RES pin is a VDDQ CMOS input. RES is not internally terminated. When RES is at LOW state the chip goes into full reset. The chip stays in full reset until RES goes to HIGH state. The Low to High transition of the RES signal is used to latch the CKE value to set the value of the termination resistors of the address and command inputs. After exiting the full reset a complete initialization is required since the full reset sets the internal settings to default. Mirror function pin: The MF pin is a VDDQ CMOS input. This pin must be hardwired on board either to a power or to a ground plane. With MF set to HIGH, the command and address pins are reassigned in order to allow for an easier routing on board for a back to back memory arrangement. Enables Boundary Scan Functionality: If Boundary Scan is not used PIN should be constantly connected to GND. Voltage Reference: VREF is the reference voltage input. Power Supply: Power and Ground for the internal logic. I/O Power Supply: Isolated Power and Ground for the output buffers to provide improved noise immunity. Please do not connect No Connect and Reserved for Future Use balls. When the MF ball is tied LOW, RFM receiver is disabled and it recommended to be driven to a static LOW state. However, either static HIGH or floating state on this pin will not cause any problem for the GDDR3 SGRAM. When the MF ball is tied HIGH, RAS(H3) becomes RFM due to mirror function and the receiver is disabled. It is recommended to be driven to a static LOW state. However, either static HIGH or floating state on this pin will not cause any problem for the GDDR3 SGRAM.

2.2
Mirror Function
The GDDR3 Graphics RAM provides a ball mirroring feature that is enabled by applying a logic HIGH on ball MF. This function allows for efficient routing in a clam shell configuration. Depending of the logic state applied on MF, the command and address signals will be assigned to different balls. The default ball configuration corresponds to MF = LOW. The DC level (HIGH or LOW) must be applied on the MF pin at power up and is not allowed to change after that. Table 3 shows the ball assignment as a function of the logic state applied on MF.

Functional Description
Mode Register Set Command (MRS)
The Mode Register stores the data for controlling the operation modes of the memory. It programs CAS latency, test mode, DLL Reset , the value of the Write Latency and the Burst length. The Mode Register must be written after power up to operate the SGRAM. During a ModeRegister Set command the address inputs are sampled and stored in the Mode Register. The Mode Register content can only be set or changed when the chip is in Idle state. For non-READ commands following a Mode Register Set a delay of tMRD must be met. The Mode Register Bitmap is supported in two configurations. The first configuration is intended to support the Mid-RangeSpeed application. The second configuration supports higher clock cycles for CAS latency and is therefore prepared to support high-speed application. The selected configuration is defined by Bit0 of EMRS2.

3.1.1
Burst length
Read and Write accesses to the GDDR3 Graphics RAM are burst oriented with burst length of 4 and 8. This value must be programmed using the Mode Register Set command (A0 .. A2). The burst length determines the number of column locations that can be accessed for a given READ or WRITE command. When a READ or WRITE command is issued, a block of columns equal to the burst length is effectively selected. All accesses for that burst take place within this block if a boundary is reached. The starting location within this block is determined by the two least significant bits A0 and A1 which are set internally to the fixed value of zero each.Reserved states should not be used, as unknown operation or incompatibility with future versions may result.
3.1.2
Burst type
Accesses within a given bank must be programmed to be sequential. This is done using the Mode Register Set command (A3). This device does not support the burst interleave mode.

The value applied at the balls A0 and A1 for the column address is "Don't care".
3.1.3
CAS Latency
The CAS latency is the delay, in clock cycles, between the registration of a READ command and the availability of the first bit of output data. If a READ command is registered at clock edge n, and the latency is m clocks, the data will be available nominally coincident with clock edge n+m. The two Mode Register setups support different CAS Latencies in terms of clock cycles. The mid-range-speed Mode Register supports latencies from 7 to 14. The high-speed Mode Register supports latencies from 10 to 17. The active Mode Register setup is selected by Bit0 of EMRS2.
3.1.4
Write Latency
The WRITE latency, WL, is the delay, in clock cycles, between the registration of a WRITE command and the availability of the first bit of input data.

The ON/OFF state of the DQ/DM receivers depends on the Write Latency. The dependence is given in Table 7.
3.1.5
Test mode
The normal operating mode is selected by issuing a Mode Register Set command with bit A7 set to zero and bits A0-A6 and A8-A11 set to the desired value.
3.1.6
DLL Reset
The normal operating mode is selected by issuing a Mode Register Set command with bit A8 set to zero and bits A0-A7 and A9-A11 set to the desired values. A DLL Reset is initiated by issuing a Mode Register Set command with bit A8 set to one and bits A0-A7 and A9-A11 set to the desired values. The GDDR3 Graphics RAM returns automatically in the normal mode of operations once the DLL reset is completed.

Extended Mode Register Set Command (EMRS1)
The Extended Mode Register is used to set the output driver impedance value, the termination impedance value, the Write Recovery time value for Write with Autoprecharge. It is used as well to enable/disable the DLL, to issue the Vendor ID and to enable/disable the Low Power mode. There is no default value for the Extended Mode Register. Therefore it must be written after power up to operate the GDDR3 Graphics RAM. The Extended Mode Register can be programmed by performing a normal Mode Register Set operation and setting the BA0 bit to HIGH and BA1 bits to LOW. All other bits of the EMR register are reserved and should be set to LOW. The Extended Mode Register must be loaded when all banks are idle and no burst are in progress. The controller must wait the specified time tMRD before initiating any subsequent operation (Figure 9). The timing of the EMRS command operation is equivalent to the timing of the MRS command operation.

FIGURE 7
Extended Mode Register Bitmap for Mid-Range-Speed Application
There are two bitmaps for the Extended Mode Register. One bitmap shown in Figure 7 is supposed to support Mid-Speed applications. The other bitmap shown in Figure 8 is more focused on the high-range-speed application. Both bitmaps distinguish different numbers in supported Write Recovery clock cycles. The mid-range bit map provides WR cycles from 4 to 11.The high-speed bitmap supports WR from 7 to 13.

Notes 1. These settings are for debugging purposes only. 2. Default termination values at Power Up. 3. The ODT disable function disables all terminators on the device. 4. If the user activates bits in the extended mode register in an optional field, either the optional field is activated (if
option implemented in the device) or no action is taken by the device (if option not implemented). 5. WR (write recovery time for auto precharge) in clock cycles is calculated by dividing tWR (in ns) and rounding up to the next integer (WR[cycles] = tWR[ns] / tCK[ns]). The mode register must be programmed to this value.

3.2.1
DLL enable
The DLL must be enabled for normal operation. DLL enable is required during power-up initialization and upon returning to normal operation after having disabled the DLL. (When the device exits self-refresh mode, the DLL is enabled automatically). Anytime the DLL is enabled, 1000 cycles must occur before a READ command can be issued.
3.2.2
WR
The WR parameter is programmed using the register bits A4, A5 and A7. This integer parameter defines as a number of clock cycles the Write Recovery time in a Write with Autoprecharge operation. The following inequality has to be complied with: WR * tCK tWR, where tCK is the clock cycle time. The high-speed bitmap supports WR from 7 to 13. The mid-range bitmap provides WR cycles from 4 to 11.
3.2.3
Termination Rtt
The data termination, Rtt, is used to set the value of the internal termination resistors. The GDDR3 DRAM supports ZQ / 4 and ZQ / 2 termination values. The termination may also be disabled for testing and other purposes.
3.2.4
Output Driver Impedance
The Output Driver Impedance extended mode register is used to set the value of the data output driver impedance. When the auto calibration is used, the output driver impedance is set nominally to ZQ / 6. If the Output Driver Impendance is changed to 30, 40 or 45 Ohms the user needs to issue 16 AREF commands separated by tRFC consecutively to make the change effective. The user must be aware that the Command bus needs to be stable for a time of tKO after each AREF.
3.2.5
Vendor Code and Revision Identification
The Manufacturer Vendor Code is selected by issuing an Extended Mode Register Set command with bit A10 set to 1 and bits A0-A9 and A11 set to the desired value. When the Vendor Code function is enabled the GDDR3 DRAM will provide the Qimonda vendor code on DQ[3:0] and the revision identification on DQ[7:4]. The code will be driven onto the DQ bus after tRIDon following the EMRS command that sets A10 to 1. The Vendor Code and Revision ID will be driven on DQ[7:0] until a new EMRS command is issued with A10 set back to 0. After tRDoff following the second EMRS command, the data bus is driven back to HIGH. This second EMRS command must be issued before initiating any subsequent operation. Violating this requirement will result in unspecified operation.

Extended Mode Register 2 Set Command (EMRS2)
The Extended Mode Register 2 is used to define the active bitmap of the Mode Register and the Extended Mode Register. The Extended Mode Register 2 must be written after power up to operate the GDDR3 Graphics RAM. The Extended Mode Register 2 can be programmed by performing a normal Mode Register Set operation and setting the BA1 bit to HIGH and BA0 bits to LOW. All bits defined as RFU in the bitmap are reserved and must be set to LOW. The Extended Mode Register 2 must be loaded when all banks are idle and no burst are in progress. The controller must wait the specified time tMRD before initiating any subsequent operation. The timing of the EMRS2 command operation is equivalent to the timing of the MRS command operation.

App Mode
The GDDR3 Graphics RAM provides two bitmaps for the Mode Register and the Extended Mode Register respectively. The Bitmaps are shown in the MRS and EMRS chapters. The Bit0 of the Extended Mode Regsiter 2 defines which one of the two bitmaps is active. Bit0 set to LOW enables the midrange bitmap and Bit0 set to HIGH enables the High-Speed bitmap.

1) The DC values define where the input slew rate requirements are imposed, and the input signal must not violate these levels in order to maintain a valid level. 2) Input slew rate = 3 V/ns. If the input slew rate is less than 3 V/ns, input timing may be compromised. All slew rates are measured between VIL(DC) and VIH(DC). 3) VIH overshoot: VIH(max) = VDDQ+0.5V for a pulse width 500ps and the pulse width cannot be greater than 1/3 of the cycle rate. VIL undershoot: VIL(min) = 0 V for a pulse width 500ps and the pulse width cannot be greater than 1/3 of the cycle rate. 4) The MF pin must be hard-wired on board to either VDD or VSS.
