HANBit HSD8M72D9A Synchronous DRAM Module 64Mbyte (8Mx72bit),DIMM with ECC based on 8Mx8, 4Banks, 4K Ref., 3.3V Part No. HSD8M72D9A GENERAL DESCRIPTION The HSD8M72D9A is a 8M x 72 bit Synchronous Dynamic RAM high density memory module. The module consists of nine CMOS 2M x 8 bit with 4banks Synchronous DRAMs in TSOP-II 400mil packages on a 168-pin glass-epoxy substrate. Two 0.33uF decoupling capacitors are mounted on the printed circuit board in parallel for each SDRAM. The HSD8M72D9A is a DIMM(Dual in line Memory Module) and is intended for mounting into 168-pin edge connector sockets. Synchronous design allows precise cycle control with the use of system clock. I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable latencies 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 3.3V DC power supply and all inputs and outputs are LVTTL-compatible.

(@ MRS) 2. MRS can be issued only at all banks precharge state. A new command can be issued after 2 CLK cycles of MRS. 3. Auto refresh functions are as same as CBR refresh of DRAM. The automatical 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 "Low" and BA1 is "High" at read, write, row active and precharge, bank B is selected. If both BA0 is "High" and BA1 is "Low" 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. If A10/AP is "High" at row precharge, BA0 and BA1 is ignored and all banks are selected. 5. During burst read or 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. 6. Burst stop command is valid at every burst length. 7. DQM sampled at positive going edge of a CLK and masks the data-in at the very CLK (Write DQM latency is 0), but makes Hi-Z state the data-out of 2 CLK cycles after.
