Kioxia Unleashes Blazing-Fast QLC Universal Flash Storage 4.1 Memory
KUALA LUMPUR, Jan 28 (Bernama) -- Kioxia Corporation, a world leader in memory solutions, announced the commencement of sampling for its new Universal Flash Storage (UFS) Ver. 4.1 embedded memory devices.
According to Kioxia in a statement, the new products utilise 4-bit-per-cell, quadruple-level cell (QLC) technology, specifically engineered for high-capacity and read-intensive applications.
These next-generation memory devices are powered by Kioxia’s eighth generation BiCS FLASH 3D flash memory, which introduces CMOS directly Bonded to Array (CBA) technology—a significant architectural advancement.
QLC UFS offers a higher bit density than traditional TLC UFS, making it an optimal choice for mobile devices and other electronics that require substantial storage capacities. Advancements in controller technology and error correction have enabled QLC to achieve this high density while sustaining competitive performance levels.
The new Kioxia devices deliver substantial performance leaps compared to the previous generation (UFS 4.0 / BiCS FLASH 6 QLC UFS). Key performance gains include a 25 per cent increase in sequential write speeds, a 90 per cent boost in random read speeds, and a 95 per cent jump in random write speeds.
The devices also show an improved Write Amplification Factor (WAF) of up to 3.5 times (with WriteBooster disabled).
Available in 512-gigabyte (GB) and one-terabyte (TB) capacities, the new UFS 4.1 devices integrate Kioxia’s advanced BiCS FLASH 3D flash memory and an embedded controller in a JEDEC-standard package. The package size has also been reduced from 11x13 millimetres (mm) to a more compact 9x13 mm.
While ideally suited for high-end smartphones and tablets, Kioxia’s QLC UFS 4.1 also supports a range of emerging product categories demanding higher capacity and performance, including personal computers (PCs), networking, AR/VR, Internet of Things (IoT), and artificial intelligence-enabled devices.
The devices are fully compliant with the UFS 4.1 specification, maintaining backward compatibility with UFS 4.0 and UFS 3.1. They also support WriteBooster for significantly enhanced write speeds.
