KSM26ED8/32ME
32GB 2Rx8 4G x 72-Bit PC4-2666
CL19 288-Pin DIMM
DESCRIPTION
Kingston's KSM26ED8/32ME is a 4G x 72-bit (32GB) DDR4-2666
CL19 SDRAM (Synchronous DRAM), 2Rx8, ECC, memory module,
based on eighteen 2G 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
