KUALA LUMPUR, Kioxia Corporation, a world leader in memory solutions, announced it has begun mass production of the industry’s first Universal Flash Storage (UFS) Ver. 4.0 embedded flash memory devices with four-bit-per-cell, quadruple-level cell (QLC) technology.
In a statement, Kioxia said QLC UFS offered a higher bit density than traditional triple-level cell (TLC) UFS, making it suitable for mobile applications that require higher storage capacities.
Advancements in controller technology and error correction have enabled QLC technology to achieve this while maintaining competitive performance.
Kioxia’s new 512 gigabytes (GB) QLC UFS achieves sequential read speeds of up to 4,200 megabytes per second (MB/s) and sequential write speeds of up to 3,200 MB/s, taking full advantage of the UFS 4.0 interface speed.
Its QLC UFS is well-suited for smartphones and tablets, as well as other next-generation applications where higher storage capacity and performance are key considerations, including personal comput
ers (PCs), networking, augmented reality (AR)/virtual reality (VR), and artificial intelligence (AI).
Kioxia was the first to introduce UFS technology and continues to develop new products. The new QLC UFS Ver. 4.0 device integrates the company’s innovative BiCS FLASH 3D flash memory and a controller in a global industry group that develops open standards for microelectronics, namely the JEDEC standard package.
Key features of KIOXIA’s QLC UFS 4.0 include support for high-speed link startup sequence (HS-LSS), which can be performed at a faster rate, significantly reducing the time by approximately 70 per cent compared to conventional methods.
In addition, the security enhancement is also notable aspect of these devices. By utilising Advanced Replay Protected Memory Block (RPMB) for secure read and write access to sensitive data, such as user credentials in the RPMB area.
The device also supports Extended Initiator ID (Ext-IID), which is intended to be used with Multi Circular Queue (MCQ) at the UFS 4.0 ho
st controller for improved random performance.
