KVR18R13S4/8

8GB 1Rx4 1G x 72-Bit PC3-14900

CL13 Registered w/Parity 240-Pin DIMM

DESCRIPTION

This document describes ValueRAM's 1G x 72-bit (8GB) DDR3-

1866 CL13 SDRAM (Synchronous DRAM), registered w/parity,

1Rx4 ECC memory module, based on eighteen 1G x 4-bit

FBGA components. The SPD is programmed to JEDEC stan-

dard latency DDR3-1866 timing of 13-13-13 at 1.5V. This 240-

pin DIMM uses gold contact fingers. The electrical and me-

chanical specifications are as follows:

FEATURES

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

•VDDQ = 1.5V (1.425V ~ 1.575V)

•933MHz fCK for 1866Mb/sec/pin

•8 independent internal bank

•Programmable CAS Latency: 13, 11, 10, 9, 8, 7, 6

•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

•On-DIMM thermal sensor (Grade B)

•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), double sided component

*Power will vary depending on the SDRAM and
