The TS32MSQ64V6M is a 32M x 64bits DDR2-667 SO-DIMM. The TS32MSQ64V6M consists of 4pcs 32Mx16its DDR2 SDRAMs in 84 ball FBGA packages and a 2048 bits serial EEPROM on a 200-pin printed circuit board. The TS32MSQ64V6M is a Dual In-Line Memory Module and is intended for mounting into 200-pin 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 operation frequencies, programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
