DESCRIPTION
Kingston's KHX1333C9D3B1K2/8G is a kit of two 512M x 64-bit
(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
