KSM26RD4/64HAR

64GB 2Rx4 8G x 72-Bit PC4-2666
CL19 Registered w/Parity 288-Pin DIMM

DESCRIPTION

Kingston's KSM26RD4/64HAR is a 8G x 72-bit (64GB)
DDR4-2666 CL19 SDRAM (Synchronous DRAM) registered w/
parity, 2Rx4, ECC, memory module, based on thirty-six 4G x
4-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

• VDDQ = 1.2V

• VPP = 2.5V

• VDDSPD = 2.41V to 2.75V

• Functionality and operations comply with the DDR4 SDRAM datasheet

• 16 internal banks

• Bank Grouping is applied, and CAS to CAS latency (tCCD_L, tCCD_S) for

the banks in the same or different bank group accesses are available

• Data transfer rates: PC4-2666, PC4-2400, PC4-2133, PC4-1866, PC4-1600

• Bi-Directional Differential Data Strobe

• 8 bit pre-fetch

• Burst Length (BL) switch on-the-fly BL8 or BC4(Burst Chop)

• Supports ECC error correction and detection

• On-Die Termination (ODT)

• Temperature sensor with integrated SPD

• This product is in compliance with the RoHS directive.

• Per DRAM Addressability is supported

• Internal Vref DQ level generation is available

• Write CRC is supported at all speed grades
