DESCRIPTION

Kingston’s KHX6400D2LLK2/2G is a kit of two low-latency

128M x 64-bit 1GB (1024MB) DDR2-800 CL4 SDRAM (Syn-

chronous DRAM) memory modules, based on sixteen 64M x

8-bit DDR2 FBGA components per module. Total kit capac-

ity is 2GB (2048MB). Each module pair has been tested to

run at DDR2 800MHz at low latency timing of 4-4-4-12 at

2.0V. The SPD is programmed to JEDEC standard latency

667Mhz timing of 5-5-5-15 at 1.8V. Each 240-pin DIMM uses

gold contact ngers and requires +1.8V. The electrical and

mechanical specications are as follows:

SPECIFICATIONS

Clock Cycle Time (tCK) CL=5 3ns (min.) / 8ns (max.)

Row Cycle Time (tRC) 54ns (min.)

Command Time (tRFC)

Refresh to Active/Refresh 105ns

Row Active Time (tRAS) 39ns (min.) / 70,000ns (max.)

Single Power Supply of +1.8V (+/- .1V)

Power 1.922 W (operating per module)

UL Rating 94 V - 0

Operating Temperature 0° C to 55° C

Storage Temperature -55° C to +125° C

FEATURES
