This document describes ValueRAM’s KVR26N19S8/8 is a 1G x 64-bit (8GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM), 1Rx8, memory module, based on eight 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:
– 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
– Single-rank
– On-board I2 serial presence-detect (SPD) EEPROM
– 16 internal banks; 4 groups of 4 banks each
– Fixed burst chop (BC) of 4 and burst length (BL) of 8
– via the mode register set (MRS)
– Selectable BC4 or BL8 on-the-fly (OTF)
– Fly-by topology
– Terminated control command and address bus
– PCB: Height 1.23” (31.25mm)
– RoHS Compliant and Halogen-Free
