240Pin DDR3L 1.35V 1866 SO-DIMM
8GB Based on 512Mx8
AQD-SD3L8GN18-MG
Description
AQD-SD3L8GN18-MG is a DDR3L 1866Mbps SO-DIMM
high-speed, memory module that use 8pcs of 512Mx 64
bits DDR3L SDRAM in FBGA package and a 4K bits
serial EEPROM on a 240-pin printed circuit board.
AQD-D3L4GN18-MG 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.
