Description
The TS128MLD72V6J is a 128Mx72bits Double Data
Rate SDRAM high density for DDR266. The
TS128MLD72V6J consists of 18pcs CMOS 64Mx8 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 TS128MLD72V6J 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.
