512MB 168PIN PC133 CL3
SDRAM DIMM With 32M X 8 3.3VOLT
Transcend information Inc
Description
The JM366S643A-75 is a 64M bit x 64 Synchronous
Dynamic RAM high densities for PC-133. The
JM366S643A-75 consists of 16pcs CMOS 32Mx8 bits
Synchronous DRAMs in TSOP-II 400mil packages and a
2048 bits serial EEPROM on a 168-pin printed circuit
board. The JM366S643A-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.
