KMM464S924T1 شرح
KMM464S924T1
Preliminary
PC100 144pin SDRAM SODIMM
KMM464S924T1 SDRAM SODIMM
8Mx64 SDRAM SODIMM based on 8Mx16, 4Banks, 4K Refresh, 3.3V Synchronous DRAMs with SPD
GENERAL DESCRIPTION
The Samsung KMM464S924T1 is a 8M bit x 64 Synchronous
Dynamic RAM high density memory module. The Samsung
KMM464S924T1 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 144-pin glass-
www.DataSheeet4pUo.xcyomsubstrate. Three 0.1uF decoupling capacitors are
mounted on the printed circuit board in parallel for each
SDRAM. The KMM464S924T1 is a Small Outline Dual In-line
Memory Module and is intended for mounting into 144-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 laten-
cies allows the same device to be useful for a variety of high
bandwidth, high performance memory system applications.
