200PIN DDR266 Unbuffered SO-DIMM
256MB With 32Mx8 CL2.5
 
Description 
The TS32MSD64V6F5 is a 32M x 64bits Double Data 
Rate SDRAM high-density for DDR266.The 
TS32MSD64V6F5 consists of 8pcs CMOS 32Mx8 bits  
Double Data Rate SDRAMs in 66 pin TSOP-II 400mil 
packages, and a 2048 bits serial EEPROM on a 200-pin 
printed circuit board. The TS32MSD64V6F5 is a Dual 
In-Line Memory Module and is intended for mounting into 
200-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.
