- New QLC technology increases storage capacity and performance
- High-Speed Link Startup Sequence reduces initialization time by 70%
- Enhanced security features effectively protect sensitive user data
The growing demand for mobile technology has increased the need for high-capacity, high-speed data storage. As digital devices continue to evolve, the industry is looking for a way to handle larger data loads while delivering fast and efficient performance.
Kioxia has now launched mass production of its latest innovation: the industry’s first QLC UFS 4.0 embedded flash memory device.
The new device is designed with quadruple-level cell (QLC) technology and comes with higher bit density and larger storage capacity thanks to Universal Flash Storage (UFS) technology.
High speed performance for demanding applications
With this new QLC UFS 4.0 device, Kioxia offers higher storage capacity within a compact structure, benefiting not only compact devices such as mobile phones and tablets, but also PCs, network systems and emerging fields such as AR, VR and AI that require robust require storage solutions.
Kioxia’s QLC UFS 4.0 device has impressive data transfer speeds, with the device achieving sequential read speeds of up to 4,200 MB/s and sequential write speeds of up to 3,200 MB/s. These speeds are achieved using the UFS 4.0 interface, which supports interface speeds of up to 23.2 Gbps per lane or 46.4 Gbps per device.
This combination of QLC storage with the latest UFS interface technology provides a significant performance boost, making it well suited for data-heavy applications. As a result, users can expect faster file transfers, smoother streaming and more efficient multitasking, especially for mobile and high-performance computing devices.
Kioxia’s new QLC UFS 4.0 device is also built on proprietary BiCS FLASH 3D flash memory, known for its durability and efficiency. The UFS 4.0 package is designed to comply with the JEDEC standard and combines this advanced memory with a dedicated controller to optimize performance. With backward compatibility with UFS 3.1, Kioxia’s UFS 4.0 devices provide an upgrade path for users.
To improve its practical application, Kioxia’s QLC UFS 4.0 device features a High-Speed Link Startup Sequence (HS-LSS), a new method that accelerates device-to-host initialization. By enabling link startup at a faster HS-G1 Rate A instead of the conventional lower rate, HS-LSS reduces link startup time by approximately 70%.
In addition to faster initialization, the device also features enhanced security capabilities with Advanced Replay Protected Memory Block (RPMB) features. These security measures protect user data by securing access to sensitive information, such as login credentials. RPMB Purge also allows users to ensure that discarded data is completely purged, adding a new layer of confidence in data protection.
In addition, Kioxia’s QLC UFS Ver. 4.0 device supports an Extended Initiator ID (Ext-IID), which is designed to work with Multi Circular Queue (MCQ) in the UFS 4.0 host controller. This feature improves random performance, a critical component for devices that require fast and distributed access to data across multiple applications. With Ext-IID, the device is better equipped to manage complex data tasks, delivering faster, more efficient performance for users with demanding workloads.
