AD64I1B16

AD64I1B16
DDR3-1600G(CL9) 240-Pin O.C. U-DIMM
2GB (256M x 64-bits)
General Description
The ADATA’s AD64I1B16 is a 256Mx64 bits 2GB(2048MB) DDR3-1600(CL9)-9-9-24 SDRAM over clocking
memory module, The SPD is programmed to JEDEC standard latency 1600Mbps timing of 9-9-9-28 at 1.5V. The
module is composed of sixteen 128Mx8 bits CMOS DDR3 SDRAMs in FBGA package and one 2Kbit EEPROM in
8pin TDFN package on a 240pin glass–epoxy printed circuit board.
The AD64I1B16 is a Dual In-line Memory Module and intended for mounting onto 240-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.
