This document describes ValueRAM's 512M x 72-bit (4GB) DDR3L-1333 CL9 SDRAM (Synchronous DRAM), low voltage, registered w/parity, 2Rx8, ECC, VLP (very low profile) memory module, based on eighteen 256M x 8-bit DDR3L-1333 FBGA components. The SPD is programmed to JEDEC standard latency DDR3-1333 timing of 9-9-9 at 1.5V. This 240-pin DIMM uses gold contact fingers.
This datasheet describes the ValueRAM KVR1333D3LD8R9SL/4GEC 4 GB DDR3L‑1333 memory module, a 240‑pin registered DIMM with parity and ECC support. It provides electrical, mechanical, and performance specifications for system designers.
Key features include JEDEC‑standard 1.35 V and 1.5 V operation, programmable CAS latency (9‑6), 667 MHz fCK, eight independent internal banks, and a low‑profile height of 0.740 in (18.75 mm). The module also offers on‑DIMM thermal sensing and internal self‑calibration.
