Kingston DRAM 4GB 2133MHz DDR4 ECC CL15 SODIMM 1Rx8
KVR21SE15S8/4


This document describes ValueRAM's 512M x 72-bit (4GB)
DDR4-2133 CL15 SDRAM (Synchronous DRAM), 1Rx8, ECC,
memory module, based on nine 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
SODIMM uses gold contact fingers. The electrical and
mechanical specifications are as follows:


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
Single-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

CL(IDD) : 15 cycles
Row Cycle Time (tRCmin) : 46.5ns(min.)
Refresh to Active/Refresh
Command Time (tRFCmin) : 260ns(min.)
Row Active Time (tRASmin) : 33ns(min.)
UL Rating : 94 V - 0
Operating Temperature : 0C to +85C
Storage Temperature : -55C to +100C
