KVR26S19D8/32 32GB 2Rx8 4G x 64-Bit PC4-2666 CL19 260-Pin SODIMM Continued >> FEATURES This document describes ValueRAM's KVR26S19D8/32 is a 4G x 64-bit (32GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM), 2Rx8, non-ECC, memory module, based on sixteen 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 ?
