DESCRIPTION
This document describes ValueRAM’s KVR32N22S6/8 is a 1G x 64-bit (8GB) DDR4-3200 CL22 SDRAM (Synchronous DRAM), 1Rx16, memory module, based on four 1G x 16-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR4-3200 timing of 22-22-22 at 1.2V. Each 288-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows: SPECIFICATIONS
CL(IDD) – 22 cycles
Row Cycle Time (tRCmin) – 45.75ns(min.)
Refresh to Active/Refresh Command Time (tRFCmin) – 350ns(min.)
Row Active Time (tRASmin) – 32ns(min.)
UL Rating – 94 V – 0
Operating Temperature – 0° C to +85° C
Storage Temperature – -55° C to +100° C
