This document describes ValueRAM's KVR26N19S6/L4 is a 512M x 64-bit (4GB) DDR4-2666 CL19 SDRAM (Synchronous DRAM), 1Rx16, VLP (very low profile) memory module, based on four 512M x 16-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR4-2666 timing of 19-19-19 at 1.2V. Each 288-pin DIMM uses gold contact fingers.

- 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
- 8 internal banks; 2 groups of 4 banks each
- Selectable BC4 or BL8 on-the-fly (OTF)
- Fly-by topology
- Terminated control command and address bus
- RoHS Compliant and Halogen-Free
