About Transcend 512MB, DDR2, 533Mhz, PC4200/4300, JetRam, CL4, 0.5 GB, DDR2, 533 MHz, 240-pin DIMM

Transcend 512MB, DDR2, 533Mhz, PC4200/4300, JetRam, CL4. Internal memory: 0.5 GB, Internal memory type: DDR2, Memory clock speed: 533 MHz, Memory form factor: 240-pin DIMM, CAS latency: 4, ECC

The JM367Q643A-5 is a 64M x 64bits DDR2-533 Unbuffered DIMM. The JM367Q643A-5 consists of 8 pcs 64Mx8bits DDR2 SDRAMs in 60 ball FBGA packages and a 2048 bits serial EEPROM on a 240-pin printed circuit board. The JM367Q643A-5 is a Dual In-Line Memory Module and 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.
