FEATURES This document describes ValueRAMs KVR26S19S8/16 is a 2G x 64-bit (16GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM), 1Rx8, non-ECC, memory module, based on eight 2G x 8-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR4-2666 timing of 19-19-19 at 1.2V. This 260-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows: CL(IDD) Row Cycle Time (tRCmin) Refresh to Active/Refresh Command Time (tRFCmin) Row Active Time (tRASmin) UL Rating Operating Temperature Storage Temperature 19 cycles 45.75ns(min.) 350ns(min.) 32ns(min.) 94 V - 0 0o C to +85o C -55o C to +100o C . 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 .
