FEATURES This document describes ValueRAM's 512M x 64-bit (4GB)
DDR3-1600 CL11 SDRAM (Synchronous DRAM) 1Rx8, memory
module, based on eight 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:
- 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 85DegC,
3.9us at 85DegC < TCASE < 95DegC
- Asynchronous Reset
- PCB : Height 0.740" (18.75mm), single sided component
