Sony to aims to commercialize 128GB and 256GB ReRAM drives in 2020

Sony announced that it is accelerating its RRAM ("Cross Point ReRAM") development with an aim to commercialize it in 2020. Sony says that its ReRAM will be cheaper than NAND, and also faster, consumer less power and heat. Sony's efforts at this stage are to develop a smart low-power ReRAM controller, reduce the power consumption and manage the thermal issues.

As can be seen in the slide above (click to enlarge), Sony says its 128GB ReRAM drives will feature 25.6 GB/s read times, 9.6 GB/s write times and will support PCIe gen5 x 5. The power consumption target is 14.6W. The larger 16-chip 256GB drives will be faster at 51.2 GB/s read and 19.2 GB/s write. The power consumption will be 27.2W.

It could be that Sony is aiming to adopt this technology for its PlayStation 5 gaming console - which will deliver a great speed boost over current SSDs.
