Storage Class Memory

As there is no established market for Storage Class Memory, the Company continues to explore speed, endurance and retention performance and are quantifying the trade-offs between these parameters. Fully quantifying the tradeoffs between these parameters will enable our future users to select the operating space which is most attractive for their future applications that require memory solutions “between” DRAM and NAND.

It will all come down to cost, speed of production and how energy efficient to displace DRAM and NAND
