Transcend Jet Ram 1GB DDR3 SDRAM 1333 M Hz Desktop Memory Module The JM1333KLU-1G is a 128M x 64bits DDR3-1333 unbuffered DIMM. The JM1333KLU-1G consists of 8pcs 128 Mx 8bits DDR3 SDRAMs in FBGA packages & a 2048 bits serial EEPROM on a 240-pin printed circuit board. The JM1333KLU-1G is a Dual In-Line Memory Module & is intended for 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.
