This document describes ValueRAM's KVR26N19D8/16 is a 2G x 64-bit (16GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM), 2Rx8, memory module, based on sixteen 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) fordata, strobe, and mask signals Low-power auto self refresh (LPASR) Data bus inversion (DBI) for data bus On-die VREFDQ generation and calibration Dual-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 8via 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
