DESCRIPTION:

Kingston's KHX3500AK2/512 is a kit of two 32M x 64-bit (256MB) DDR434 CL2.5 SDRAM

(Synchronous DRAM) memory modules. Total kit capacity is 512MB. The components on each

module include eight 32M x 8-bit (8M x 8-bit x 4 Bank / 217MHz, 4.6ns) DDR434 SDRAM in TSOP

packages. Each 184-pin DIMM uses gold contact fingers and requires +2.6V. The electrical and

mechanical specifications are as follows:

FEATURES:

Power supply : Vdd: 2.6V ± 0.2V, Vddq: 2.6V ± 0.2V

Double-data-rate architecture; two data transfers per clock cycle

Bidirectional data strobe(DQS)

Differential clock inputs(CK and CK)

DLL aligns DQ and DQS transition with CK transition

Programmable Read latency 2.5 (clock)

Programmable Burst length (2, 4, 8)

Programmable Burst type (sequential & interleave)

Timing Reference: 2.5-3-3-7-1 at +2.6V

Edge aligned data output, center aligned data input

Auto & Self refresh, 7.8us refresh interval (8K/64ms refresh)

Serial presence detect with EEPROM
