HANBit HSD16M64D8B Synchronous DRAM Module 128Mbyte (16Mx64-Bit), DIMM, 4Banks, 4K Ref., 3.3V Part No. HSD16M64D8B GENERAL DESCRIPTION The HSD16M64D8B is a 16M x 64 bit Synchronous Dynamic RAM high density memory module. The module consists of eight CMOS 2M x 16 bit with 4banks Synchronous DRAMs in TSOP-II 400mil packages on a 168-pin glass-epoxy substrate. Two 0.1uF decoupling capacitors are mounted on the printed circuit board in parallel for each SDRAM. The HSD16M64D8B 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.

HANBit HSD16M64D8B PIN FUNCTION DESCRIPTION Pin Name CLK System clock /CE Chip enable Input Function Active on the positive going edge to sample all inputs. Disables or enables device operation by masking or enabling all inputs except CLK, CKE and DQM Masks system clock to freeze operation from the next clock cycle. CKE should be enabled at least one cycle prior to new command. CKE Clock enable Disable input buffers for power down in standby. CKE should be enabled 1CLK+tSS prior to valid command. Row/column addresses are multiplexed on the same pins. A0 ~ A11 Address Row address : RA0 ~ RA11, Column address : CA0 ~ CA8 Selects bank to be activated during row address latch time. BA0 ~ BA1 Bank select address Selects bank for read/write during column address latch time. Latches row addresses on the positive going edge of the CLK with RAS low. /RAS Row address strobe Enables row access & precharge. Column address Latches column addresses on the positive going edge of the CLK with CAS low. /CAS strobe Enables column access. Enables write operation and row precharge. /WE Write enable Latches data in starting from CAS, WE active. Data input/output Makes data output Hi-Z, tSHZ after the clock and masks the output. DQM0 ~ 7 mask DQ0 ~ 63 Data input/output Power Blocks data input when DQM active. (Byte masking) Data inputs/outputs are multiplexed on the same pins.

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.
