MPMB62D-68KX3 256MB PC-2700 DDR DIMM MPMB62D-68KX3 PC-2700 CL2.5 184pin DDR DIMM 32Mx64 DDR DIMM based on 16Mx8 DDR SDRAMs with SPD DESCRIPTION The MPMB62D-68KX3 is 32M bit x 64 Double Data Rate Synchronous Dynamic RAM high density memory module based on 128Mb DDR SDRAM respectively. The MPMB62D-68KX3 consists of sixteen CMOS 16M × 8 bit with 4 banks Double Data Rate Synchronous DRAMs in TinyBGA package and a 2K EEPROM in 8-Pin TSSOP package mounted on a 184pin glass-epoxy substrate. Two 0.1µF decoupling capacitors are mounted on the printed circuit board in parallel for each DDR SDRAM. The MPMB62D-68KX3 is a Dual In- line Memory Module and is intended for mounting into 184pin edge connector sockets. Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges of every clock cycle. 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.

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. 3. 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. 4. A write command can be applie d with tRCD satisfied after this command. 5. For registered DINNs, tCL and tCH are ≥ 45% of the period including both the half period jitter (tJIT(HP)) of the PLL and the half period jitter due to cross talk (tJIT(crosstalk)) on the DIMM. 6.

Auto refresh functions are same as the CBR refresh of DRAM. The automatically precharge without row precharge command is meant by "Auto". Auto/self refresh can be issued only at all banks precharge state. 4. BA0 ~ BA1 : Bank select addresses. If both BA0 and BA1 are "Low" at read, write, row active and precharge, bank A is selected. If both BA0 is "High" and BA1 is "Low" at read, write, row active and precharge, bank B is selected. If both BA0 is "Low" and BA1 is "High" at read, write, row active and precharge, bank C is selected. If both BA0 and BA1 are "High" at read, write, row active and precharge, bank D is selected. 5. If A10 /AP is "High" at row precharge, BA0 and BA1 are ignored and all banks are selected. 6. During burst write with auto precharge, new read/write command can not be issued. Another bank read/write command can be issued after the end of burst. New row active of the associated bank can be issued at tRP after the end of burst. 7. Burst stop command is valid at every burst length. 8. DM sampled at the rising and falling edges of the DQS and Data-in are masked at the both edges (Write DM latency is 0). 9. This combination is not defined for any function, which means "No Operation (NOP)" in DDR SDRAM.
