KMM366S1623CT KMM366S1623CT SDRAM DIMM Preliminary PC100 SDRAM MODULE 16Mx64 SDRAM DIMM based on 8Mx8, 4Banks, 4K Refresh, 3.3V Synchronous DRAMs with SPD GENERAL DESCRIPTION The Samsung KMM366S1623CT is a 16M bit x 64 Synchronous Dynamic RAM high density memory module. The Samsung KMM366S1623CT consists of sixteen CMOS 8M x 8 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. Two 0.1uF decoupling capacitors are mounted on the printed circuit board in parallel for each SDRAM. The KMM366S1623CT 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 [ ... ]
