M464S3254DTS
Rev. 0.0 Jan. 2002
PC133/PC100 SODIMM
The Samsung M464S3254DTS is a 32M bit x 64 Synchronous
Dynamic RAM high density memory module. The Samsung
M464S3254DTS consists of eight CMOS 16M x 16 bit with
4banks Synchronous DRAMs in TSOP-II 400mil package and a
2K EEPROM in 8-pin TSSOP package on a 144-pin glass-epoxy
substrate. Three 0.1uF decoupling capacitors are mounted on
the printed circuit board in parallel for each SDRAM. The
M464S3254DTS is a Small Outline Dual In-line Memory Module
and is intended for mounting into 144-pin edge connector sock-
ets.
Synchronous design allows precise cycle control with the use of
system clock. I/O transactions are possible on every clock cycle.
Range of operating frequencies, programmable latencies allows
the same device to be useful for a variety of high bandwidth,
high performance memory system applications.
