The new 512GB device brings higher QLC bit density to UFS

     KIOXIA Europe GmbH has announced that it has started mass production of the industry's first UFS Ver.4.0 embedded flash memory device with 4-bit/cell QLC technology. QLC UFS offers a higher bit density than traditional TLC UFS, making it ideal for mobile applications that require higher storage capacity. Advances in controller technology and error correction technology have enabled QLC technology to achieve this goal while maintaining competitive performance. The company's new 512GB QLC UFS achieves sequential read speeds of up to 4,200MB/s and sequential write speeds of up to 3,200MB/s, taking full advantage of UFS 4.0 interface speeds.

     The device is ideal for smartphones and tablets, as well as other next-generation applications where higher storage capacity and performance are key considerations, including pc, networking, AR/VR, iot, and artificial intelligence. Key features include support for the high-speed Link Startup Sequence (HS-LSS) feature, enhanced security, and support for extended Initiator ids (Ext-IID).

     The company was the first to introduce UFS technology and continues to develop new and innovative flash memory products. The new QLC UFS Ver.4.0 device integrates the company's innovative BiCS FLASH 3D flash memory and the controller in the JEDEC standard package. UFS 4.0 integrates MIPI M-PHY 5.0 and UniPro 2.0 to support maximum theoretical interface speeds of 23.2Gbps per channel or 46.4Gbps per device. UFS 4.0 is backward compatible with UFS 3.1.

     Axel Stormann, Chief Technology Officer and Vice President, KIOXIA Europe GmbH, comments: "KIOXIA first sampled 512Gbps of QLC UFS 3.1 in 2022, and we are very excited to bring the first QLC UFS Ver.4.0 version into production, expanding our UFS Memory product range while demonstrating our commitment to storage technology development," And enable customers to meet growing storage demands." QLC technology offers higher density and cost efficiency, making it particularly suitable for data-intensive applications that require superior interface performance."
