HANBit HSD8M32M4V Synchronous DRAM Module 32Mbyte ( 8M x 32-Bit ) 72pin-SIMM based on 16Mx8, 4Banks, 4K Ref., 3.3V Part No. HSD8M32M4V GENERAL DESCRIPTION The HSD8M32M4V is a 8M x 32 bit Synchronous Dynamic RAM high density memory module. The module consists of four CMOS 2M x 8 bit with 4banks Synchronous DRAMs in TSOP-II packages mounted on a 72-pin, FR-4-printed circuit board. Two 0.01uF decoupling capacitor is mounted on the printed circuit board in parallel for each SDRAM. The HSD8M32M4V is a SIMM designed. 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.

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.
