DESCRIPTION
Kingston’s KHX1333C7AD3K2/4G is a kit of two 256M x
64-bit (2GB) DDR3-1333MHz CL7 SDRAM (Synchronous
DRAM) memory modules, based on sixteen 128M x 8-bit
DDR3 FBGA components per module. Total kit capacity is
4GB. Each module has been tested to run at DDR3-1333MHz
at a low latency timing of 7-7-7-20 at 1.65V. The SPDs are
programmed to JEDEC standard latency DDR3-1333MHz
timing of 9-9-9 at 1.5V. This 240-pin DIMM uses gold contact
ngers and requires +1.5V. The JEDEC standard electrical
and mechanical specications are as follows:
FEATURES
• JEDEC standard 1.5V ± 0.075V Power Supply
• VDDQ = 1.5V ± 0.075V
• 667MHz fCK for 1333Mb/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(DDR3-1333)
• 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 y 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
