so-ddr3 4gb 1333mhz

В наличии комплект из двух планок, цена за одну.

ValueRAM's KVR13S9S8K2/8 is a kit of two 512M x 64-bit

(4GB) DDR3-1333 CL9 SDRAM (Synchronous DRAM), 1Rx8

memory modules, based on eight 512M x 8-bit FBGA compo-

nents per module. Total kit capacity is 8GB. The SPDs are

programmed to JEDEC standard latency DDR3-1333 timing of

9-9-9 at 1.5V. Each 204-pin SODIMM uses gold contact fingers.

The 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 1.18” (30mm), double sided component
