Description 
The TS128MLD72V6E is a 128Mx72bits Double Data 
Rate SDRAM high density for DDR266. The 
TS128MLD72V6E consists of 36pcs CMOS 64Mx4 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 TS128MLD72V6E 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.
