HANBit HDD32M64B8 DDR SDRAM Module 256Mbyte (32Mx64bit), based on32Mx8,4Banks, 8K Ref., SO-DIMM Part No. HDD32M64B8 GENERAL DESCRIPTION The HDD32M64B8 is a 32M x 64 bit Double Data Rate(DDR) Synchronous Dynamic RAM high-density memory module. The module consists of eight CMOS 32M x 8 bit with 4banks DDR SDRAMs in 66pin TSOP-II 400mil packages and 2K EEPROM in 8-pin TSSOP package on a 200-pin glass-epoxy. Four 0.1uF decoupling capacitors are mounted on the printed circuit board in parallel for each DDR SDRAM. The HDD32M64B8 is a SO-DIMM(Small Outline Dual in line Memory Module) .Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges of DQS. Range of operating frequencies, programmable latencies and burst lengths allows the same device to be useful for a variety of high bandwidth, high performance memory system applications. All module components may be powered from a single 2.5V DC power supply and all inputs and outputs are SSTL_2 compatible.

HANBit HDD32M64B8 PIN FUNCTION DESCRIPTION Pin CK, /CK Name Input Function CK and CK are differential clock inputs. All address and control input signals are sam-pled on the positive edge of CK and negative edge of CK. Output (read) data Clock is referenced to both edges of CK. Internal clock signals are derived from CK/CK. CKE HIGH activates, and CKE LOW deactivates internal clock signals, and device input buffers and output drivers. Deactivating the clock provides PRECHARGE POWER-DOWN and SELF REFRESH operation (all banks idle), or ACTIVE POWER-DOWN(row ACTIVE in any bank). CKE is synchronous for all functions CKE Clock Enable except for disabling outputs, which is achieved asynchronously. Input buffers, excluding CK, CK and CKE are disabled during power-down and self refresh modes, providing low standby power. CKE will recognizean LVCMOS LOW level prior to VREF being stable on power-up. CS enables(registered LOW) and disables(registered HIGH) the command decoder. /CS All commands are masked when CS is registered HIGH. CS provides for external Chip Select bank selection on systems with multiple banks. CS is considered part of the command code. Row/column addresses are multiplexed on the same pins. A0 ~ A12 Address BA0 ~ BA1 Bank select address /RAS Row address strobe /CAS Column strobe /WE Write enable DQS0 ~ 7 Data Strobe Row address : RA0 ~ RA12, Column address : CA0 ~ CA9 BA0 and BA1 define to which bank an ACTIVE, READ, WRITE or PRE-CHARGE command is being applied. Latches row addresses on the positive going edge of the CLK with /RAS low. address Enables row access & precharge. Latches column addresses on the positive going edge of the CLK with /CAS low. Enables column access. Enables write operation and row precharge. Latches data in starting from /CAS, /WE active. Output with read data, input with write data. Edge-aligned with read data, centered in write data. Used to capture write data. DM is an input mask signal for write data. Input data is masked when DM is sampled HIGH along with that input data during a WRITE access. DM is sampled DM0~7 Input Data Mask on both edges of DQS. DM pins include dummy loading internally, to matches the DQ and DQS load-ing. DQ0 ~ 63 Data input/output Data inputs/outputs are multiplexed on the same pins.

The case shown(DQS going from High_Z to logic Low) applies when no writes were previously in progress on the bus. If a previous write was in progress, DQS could be High at this time, depending on tDQSS. 4. The maximum limit for this parameter is not a device limit. The device will operate with a great value for this parameter, but system performance (bus turnaround) will degrade accordingly.
