DESCRIPTION
This document describes ValueRAM’s KVR32N22S6/4 is a 512M
x 64-bit (4GB) DDR4-3200 CL22 SDRAM (Synchronous DRAM),
1Rx16, memory module, based on four 512M 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:
