WD plans to mass-make 162-layer NAND by the close of the calendar year, around 200 levels by 2024

In a nutshell: Western Digital strategies to begin mass-generating 162-layer BiCS6 3D NAND, which is probably to be made use of in PCIe 5 SSDs by the conclude of this 12 months. The enterprise is also operating on NAND with 200+ levels intended for datacenter storage, PLC, and techniques to bond with each other various 3D NAND wafers to raise the variety of layers.

Western Electronic, alongside one another with companion Kioxia, just gave us a glimpse at their roadmap for the following couple of a long time of NAND enhancement. The firm plans to introduce its 6th era BiCS shortly, which will element 162 levels in TLC and QLC configurations.

Whilst that could not audio so outstanding thinking about opponents like Micron have experienced 176-layer NAND for a while now, WD statements they will shrink the memory mobile dimension by employing a new substance, ensuing in lesser die sizes.

The firm hopes that this will enable them to establish less costly storage gadgets that conduct just as perfectly. Mass production of BiCS6 3D NAND is scheduled to start in late 2022, with WD organizing to use these chips in merchandise ranging from inexpensive USB drives to PCIe 5. SSDs.

WD also talked about their impending BiCS+ memory with in excess of 200 layers, which is established to get there by 2024. It will feature 55 per cent more bits for each wafer, 60 % better transfer speed, and a 15 percent larger write pace in contrast to BiCS6.

It is value noting that BiCS+ is intended to be made use of only in datacenter SSDs, as the business programs to supply a distinct course of 2xx-layer NAND for client storage, dubbed BiCS-Y.

Western Electronic additionally shared that they are working on several technologies to make improvements to density and capacity, together with PLC, and that they are organizing to create NAND with 500+ levels inside of the up coming ten years.
