DDR3 VLP Unbuffered DIMM DDR3 VLP Unbuffered DIMM is high-speed, low power memory module that use DDR3 SDRAM in FBGA package and a 2048 bits serial EEPROM on a 240-pin printed circuit board. DDR3 VLP Unbuffered DIMM 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. Features • RoHS compliant products. • JEDEC standard 1.5V ± 0.075V Power supply • VDDQ=1.5V ± 0.075V • Pin Identification Symbol Function A0~A15, BA0~BA2 Address/Bank input DQ0~DQ63 Bi-direction data bus.
