DESCRIPTION

This document describes ValueRAM's 256M x 64-bit (2GB)

DDR3-1600 CL11 SDRAM (Synchronous DRAM) 1Rx16,

memory module, based on four 256M x 16-bit FBGA compo-

nents. The SPD is programmed to JEDEC standard latency

DDR3-1600 timing of 11-11-11 at 1.5V. This 204-pin SODIMM

uses gold contact fingers. The electrical and mechanical

specifications are as follows:

FEATURES

•JEDEC standard 1.5V (1.425V ~1.575V) Power Supply

•VDDQ = 1.5V (1.425V ~ 1.575V)

•800MHz fCK for 1600Mb/sec/pin

•8 independent internal bank

•Programmable CAS Latency: 11, 10, 9, 8, 7, 6, 5

•Programmable Additive Latency: 0, CL - 2, or CL - 1 clock

•8-bit pre-fetch

•Burst Length: 8 (Interleave without any limit, sequential with

starting address “000” only), 4 with tCCD = 4 which does not

allow seamless read or write [either on the fly using A12 or MRS]

•Bi-directional Differential Data Strobe

•Internal(self) calibration : Internal self calibration through ZQ

pin (RZQ : 240 ohm ± 1%)

•On Die Termination using ODT pin

•Average Refresh Period 7.8us at lower than TCASE 85°C,

3.9us at 85°C < TCASE < 95°C

•Asynchronous Reset

•PCB : Height 1.180” (30.00mm), single sided component
