Silicon Power 512MB DDR1 DIMM 400 M Hz Laptop Memory Module The SP512MBSDU400O02 is a 64M x 8bits Double Data Rate SDRAM high-density for DDR1-400. The SP512MBSDU400O02 consists of 8pcs CMOS 64 Mx 8 bits Double Data Rate SDRAMs in 66 pin TSOP package, & a 2048 bits serial EEPROM on a 200-pin printed circuit board. The SP512MBSDU400O02 is a Dual In-Line Memory Module & is intended for mounting into 200-pin edge connector sockets. Synchronous design allows precise cycle control with the use ofsystem clock. Data I/O transactions are possible on both edges of DQS. Range of operation frequencies, programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
