260Pin DDR4 2400 1.2V SO-DIMM
16GB Based on 1024Mx8
AQD-SD4U16E24-HE
Description
AQD-SD4U16E24-HE is a DDR4 2400Mbps ECC
SO-DIMM high-speed, memory module that use 18pcs of
1024M x 8 bits DDR4 SDRAM in FBGA package and a
4K bits serial EEPROM on a 260-pin printed circuit board.
AQD-SD4U8GE24-HE is a Dual In-Line Memory Module
and is intended for mounting into 260-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.
