512MB 184 PIN DDR333 DDR
SDRAM DIMM With 32Mx8 2.5VOLT
Description
The JM366D643A-60 is a 64M x 64bits Double Data Rate
SDRAM high density for DDR333. The JM366D643A-60
consists of 16pcs CMOS 32Mx8 bits Double Data Rate
SDRAMs in 66 pin TSOP-II 400mil packages and a 2048
bits serial EEPROM on a 184-pin printed circuit board.
The JM366D643A-60 is a Dual In-Line Memory Module
and is intended for mounting into 184-pin edge connector
sockets.
Synchronous design allows precise cycle control with the
use of system clock. Data I/O transactions are possible
on both edges of DQS. Range of operation frequencies,
programmable latencies allow the same device to be
useful for a variety of high bandwidth, high performance
memory system applications.
