Partnership Puts ReRAM in SSDs

TORONTO — Solid state drives (SSDs) are pretty much synonymous with NAND flash, but there have been attempts to use a different persistent memory with varying degrees of success.

Mobiveil Inc. and Crossbar Inc. recently announced they are collaborating to use resistive random access memory (ReRAM) in an SSD. The collaboration will apply Mobiveil's NVMe SSD IP to Crossbar's ReRAM IP blocks. The goal is to enable 10 times more IOPs at one-tenth of the latencies of flash NVME SSDs to speed up access to frequently requested information in large data centers, the companies told EE Times in a joint telephone interview.

Mobiveil CEO Ravi Thummarukudy said the company's NVMe, PCIe and DDR3/4 controllers can easily be adapted to accommodate the Crossbar ReRAM architecture, which is capable of six-million 512B IOPS below 10us latency. He said Mobiveil's NVM Express Controller architecture is designed to optimize link and throughput utilization, latency, reliability, power consumption and silicon footprint, and can be used along with its PCI Express (PCIe) controller and Crossbar's ReRAM controller.
