M366S1654CTS
PC133/PC100 Unbuffered DIMM
M366S1654CTS SDRAM DIMM
16Mx64 SDRAM DIMM based on 16Mx16, 4Banks, 8K Refresh, 3.3V Synchronous DRAMs with SPD
GENERAL DESCRIPTION
The Samsung M366S1654CTS is a 8M bit x 64 Synchronous
Dynamic RAM high density memory module. The Samsung
M366S1654CTS consists of four CMOS 8M x 16 bit with 4banks
Synchronous DRAMs in TSOP-II 400mil package and a 2K
EEPROM in 8-pin TSSOP package on a 168-pin glass-epoxy
substrate.Three 0.1uF decoupling capacitors are mounted on
the printed circuit board in parallel for each SDRAM.
The M366S1654CTS is a Dual In-line Memory Module and is
intended for mounting into 168-pin edge connector sockets.
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.
