128MB 168Pin PC133 CL3
SDRAM DIMM With 16Mx8 3.3VOLT
Transcend Information Inc.
Description
The JM317S643A-75 is a 16M bit x 64 Synchronous
Dynamic RAM high density for PC-133. The
JM317S643A-75 consists of 8pcs CMOS 16Mx8 bits
Synchronous DRAMs in TSOP-II 400mil packages and
a 2048 bits serial EEPROM on a 168-pin printed circuit
board. The JM317S643A-75 is a 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 operation frequencies,
programmable latencies allows the same device to be
useful for a variety of high bandwidth, high performance
memory system applications.
