This Memory module is a 128M x 8bits Double Data Rate SDRAM high-density for DDR2-800.It consists of 8pcs CMOS 128Mx8 bits Double Data Rate SDRAMs in 60 ball FBGA packages, and a 2048 bits serial EEPROM on a 240-pin print circuit board. The SP001GBLRU800S02 is a Dual In-Line Memory Module and is intend before mounting into 240-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.
