DESCRIPTION:

This document describes ValueRAM's 128M x 72-bit 1GB (1024MB) DDR3-1066 CL7 SDRAM (Synchronous DRAM)

ECC memory module, based on eighteen 64M x 8-bit DDR3-1066 FBGA components. The SPD is programmed to

JEDEC standard latency 1066Mhz timing of 7-7-7 at 1.5V. This 240-pin DIMM uses gold contact fingers and requires

+1.5V. The electrical and mechanical specifications are as follows:

FEATURES:

JEDEC standard 1.5V ± 0.075V Power Supply

VDDQ = 1.5V ± 0.075V

533MHz fCK for 1066Mb/sec/pin

8 independent internal bank

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

Posted CAS

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

Programmable CAS Write Latency(CWL) = 7(DDR3-1066)

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 then TCASE 85°C, 3.9us at 85°C < TCASE . 95°C

Asynchronous Reset

1066Mbps CL7 doesn’t have backward compatibility with 800Mbps CL5

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

PERFORMANCE:

CL(IDD) 7 cycles

Row Cycle Time (tRCmin) 50.63ns (min.)

Refresh to Active/Refresh Command Time (tRFCmin) 90ns

Row Active Time (tRASmin) 37.5ns (min.)

Power TBD W (operating)

UL Rating 94 V - 0

Operating Temperature 0

C to 85

Storage Temperature -55
