260 Pin DDR4 1.2V 2400 SO-DIMM
8GB Based on 1Gx8
AQD-SD4U8GN24-SE
Description
DDR4 1.2V SO-DIMM is high-speed, low power memory
module that use 1Gx8bits DDR4 SDRAM in FBGA
package and a 4096 bits serial EEPROM on a 260-pin
printed circuit board. DDR4 1.2V SO-DIMM 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.
