Kioxia Advances Development of UFS Ver. 3.1 Embedded Flash Memory Devices With Quad-level-cell (QLC)

Kioxia Corporation, a world leader in memory solutions, today announced the launch of Universal Flash Storage (UFS) Ver. 3.1 [1] embedded flash memory devices utilizing the company's innovative 4-bit per cell quad-level-cell (QLC) technology. For applications needing high density, such as cutting-edge smartphones, Kioxia's QLC technology enables the capability to achieve the highest densities available in a single package.

Kioxia's UFS proof of concept (PoC) device is a 512 gigabyte prototype that utilizes the company's 1 terabit (128 gigabyte) BiCS FLASH 3D flash memory with QLC technology, and is now sampling to OEM customers. The PoC device is designed to meet the increasing performance and density requirements of mobile applications driven by higher resolution images, 5G networks, 4K plus video and the like.
The samples are POC devices under development and have some feature limitations. Furthermore, specifications of the devices are subject to change without prior notice.

In every mention of a Kioxia product: Product density is identified based on the density of memory chip(s) within the Product, not the amount of memory capacity available for data storage by the end user. Consumer-usable capacity will be less due to overhead data areas, formatting, bad blocks, and other constraints, and may also vary based on the host device and application. For details, please refer to applicable product specifications.

Stop giving us lower performance for the current price... on other hand more capacity... naaa, not worth it.

No. Just no. TLC is bad enough that we have to deal with SLC caching shenanigans and having SATA SSD type write speeds after the cache is exhausted. With QLC write speeds will get into hard drive territory.

Still no 1TB UFS 3.1 for some reason.

QLC should not be a problem in a mobile device.

Oh screw THAT. The last thing we need in a phone is this QLC garbage.

An opinion not supported by merit.

Seems like whenever QLC is mentioned everyone looses their minds jeez

If they can produce loads of it at a good price maybe we'll finally be rid of eMMC which should have left the scene long ago

That's because it's low durability crap and we're trying to send the message to industry decision makers that it is unacceptable and they should be looking for a better option instead of wasting their time trying to make the most of something the is inherently and fundamentally flawed. Even the highest end TLC is only just passable. QLC is flat out garbage.

eMMC might be slow, but it's P/E cycle durability is part way inbetween MLC and TLC NAND. For that reason eMMC is preferable.
