The JM1600KSN-4G is a 512M x 64bits DDR3-1600 SO-DIMM. The JM1600KSN-4G consists of 16pcs256Mx8bits DDR3 SDRAMs FBGA packages and a 2048 bits serial EEPROM on a 204-pin printed circuit board.The JM1600KSN-4G is a Dual In-Line Memory Module and is intended for mounting into 204-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.
