DESCRIPTION

Kingston's KHX1333C9D3B1RK2/8G is a kit of two 512M x 64bit (4GB) DDR3-1333 CL9 SDRAM (Synchronous DRAM), 2Rx8 memory modules, based on sixteen 256M x 8-bit FBGA components per module. Total kit capacity is 8GB. The SPD's are programmed to JEDEC standard latency DDR3-1333 timing of 9-9-9 at 1.5V. Each 240-pin DIMM uses gold contact fingers. The JEDEC 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)

• 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 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
