HSD8M64F8V/VA
Synchronous DRAM Module 64Mbyte ( 8M x 64-Bit ) SMM based on
8Mx8, 4Banks, 4K Ref., 3.3V
Part No. HSD8M64F8V/VA
GENERAL DESCRIPTION
The HSD8M64F8V/VA is a 8M x 64 bit Synchronous Dynamic RAM high density memory module. The module consists
of eight CMOS 2M x 8 bit with 4banks Synchronous DRAMs in TSOP-II packages is mounted on a 120-pin, double-sided,
FR-4-printed circuit board., Two 0.1uF decoupling capacitors are mounted on the printed circuit board in parallel for each
SDRAM. The HSD8M64F8V/VA is a SMM (Stackable Memory Module) designed and is intended for mounting into two 60pin 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.

Notes :
1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time and
then rounding off to the next higher integer.
2. Minimum delay is required to complete write.
3. All parts allow every cycle column address change.
4. In case of row precharge interrupt, auto precharge and read burst stop.

Notes :
1. Parameters depend on programmed CAS latency.
2. If clock rising time is longer than 1ns, (tr/2-0.5)ns should be added to the parameter.
3. Assumed input rise and fall time (tr & tf) = 1ns.
If tr & tf is longer than 1ns, transient time compensation should be considered, ie., [(tr + tf)/2-1]ns should be added to
the parameter.

Notes :
1. OP Code : Operand code
A0 ~ A11 & BA0 ~ BA1 : Program keys. (@ 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. (Read DQM latency is 2)
