This document describes ValueRAM's 512M x 72-bit (4GB)
DDR3-1333 CL9 SDRAM (Synchronous DRAM), 2Rx8, ECC,
 Compatibility Tested, memory module, based on eighteen
256M x 8-bit FBGA components. The SPD is programmed to
JEDEC standard latency DDR3-1333 timing of 9-9-9 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)
• 667MHz fCK for 1333Mb/sec/pin
• 8 independent internal bank
• Programmable CAS Latency: 9, 8, 7, 6
• Programmable Additive Latency: 0, CL - 2, or CL - 1 clock
• Programmable CAS Write Latency(CWL) = 7 (DDR3-1333)
• 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
• Bi-directional Differential Data Strobe
• Thermal Sensor Grade B
• 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 1.18” (30mm), double sided component
