KSM26ES8/8HD

8GB 1Rx8 1G x 72-Bit PC4-2666
CL19 288-Pin DIMM

DESCRIPTION

Kingston's KSM26ES8/8HD is a 1G x 72-bit (8GB) DDR4-2666
CL19 SDRAM (Synchronous DRAM), 1Rx8, ECC, memory module,
based on nine 1G x 8-bit FBGA components. The SPD is
programmed to JEDEC standard latency DDR4-2666 timing of
19-19-19 at 1.2V. Each 288-pin DIMM uses gold contact fingers. The
electrical and mechanical specifications are as follows:

FEATURES

• Power Supply: VDD = 1.2V Typical

• VDDQ = 1.2V Typical

• VPP = 2.5V Typical

• VDDSPD = 2.2V to 3.6V

• Nominal and dynamic on-die termination (ODT) for
data, strobe, and mask signals

• Low-power auto self refresh (LPASR)

• Data bus inversion (DBI) for data bus

• On-die VREFDQ generation and calibration
