This document describes ValueRAM's 1G x 64-bit (8GB) DDR3-1600 CL11 SDRAM (Synchronous DRAM) 2Rx8, memory module, based on sixteen 512M x 8-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR3-1600 timing of 11-11-11 at 1.5V. This 240-pin DIMM 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
??? 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), double sided component
