This is a 256Mx64 bits 2GB(2048MB) DDR3-1600(CL11)-11-11-28 SDRAM memory module, The SPD is programmed to JEDEC standard latency 1600Mbps timing of 11-11-11-28 at 1.35V. The module is composed of four 256Mx16bit CMOS DDR3 SDRAMs in FBGA package and one 2Kbit EEPROM in 8pin TDFN package on a 204pin glass–epoxy printed circuit board.
The module is a Dual In-line Memory Module and intended for mounting onto 204 pins edge connector sockets. Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges of DQS. Range of operating frequencies, programmable latencies and burst lengths allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
