KVR21N15S8K2/8
8GB (4GB 1Rx8 512M x 64-Bit x 2 pcs.) PC4-2133
CL15 288-Pin DIMM Kit
DESCRIPTION
This document describes ValueRAM's KVR21N15S8K2/8 is a
kit of two 512M x 64-bit (4GB) DDR4-2133 CL15 SDRAM
(Synchronous DRAM), 1Rx8, memory modules, based on eight
512M x 8-bit FBGA components. Total kit capacity is 8GB. The
SPD is programmed to JEDEC standard latency DDR4-2133
timing of 15-15-15 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) for
data, strobe, and mask signals
• Low-power auto self refresh (LPASR)
• Data bus inversion (DBI) for data bus
