GENERAL DESCRIPTION

The HSD16M64F8V/VA is a 16M x 64 bit Synchronous Dynamic RAM high density memory module. The module

consists of eight CMOS 4M 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 HSD16M64F8V/VA is a SMM (Stackable Memory Module) designed and is intended for

mounting into two 60-pin 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.
