184Pin DDR400 Registered DIMM
2GB with 128Mx4 CL3
TS256MDR72V4S
Description
Placement
The TS256MDR72V4S is a 256M x 72bits Double Data
Rate
SDRAM
high-density
for
DDR400.
The
TS256MDR72V4S consists of 36pcs CMOS 128Mx4 bits
Double Data Rate SDRAMs in 60 ball FBGA packages,
2pcs drive ICs for input control signal, 1pcs PLL, and a
2048 bits serial EEPROM on a 184-pin printed circuit
board. The TS256MDR72V4S is a Dual In-Line Memory
Module and is intended for mounting into 184-pin edge
A
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,
B
programmable latencies allow the same device to be useful
for a variety of high bandwidth, high performance memory
system applications.
