Memory Module Specifications
KVR21S15D8/8
8GB 2Rx8 1G x 64-Bit PC4-2133
CL15 260-Pin SODIMM
DESCRIPTION
This document describes ValueRAM's 1G x 64-bit (8GB)
DDR4-2133 CL15 SDRAM (Synchronous DRAM), 2Rx8,
non-ECC, memory module, based on sixteen 512M x 8-bit
FBGA components. The SPD is programmed to JEDEC
standard latency DDR4-2133 timing of 15-15-15 at 1.2V. This
260-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
• On-die VREFDQ generation and calibration
• Dual-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
• PCB: Height 1.18” (30.00mm)
• RoHS Compliant and Halogen-Free
