It was initially launched in 2009 at the International Supercomputing Conference by Irvine, California, based company, Netlist Inc.
It was never a JEDEC standard, and the main server vendors supporting it were IBM and Hewlett Packard Enterprise.
HCDIMM is a 240-pin, 72 bit-wide, load reduced, DDR3 SDRAM dual in-line memory module (DIMM).
According to Cirrascale, "while LRDIMM requires a special BIOS configuration, HyperCloud provides seamless plug-and-play operation with past, current and future generations of Intel processors.
"[1] The logic function embedded into the register device and the isolation devices used on the HCDIMM performs rank multiplication and load reduction functions which allows the system to increase its performance and access high capacity memory modules.
