- New QLC technology improves 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 large-capacity and high-speed data storage. As digital devices continue to evolve, the industry is looking for a way to handle larger data loads while providing fast and efficient performance.
Kioxia has begun mass production of its latest innovation: the industry’s first QLC UFS 4.0 embedded flash memory device.
The new device is designed using Quad Level Cell (QLC) technology, which benefits from Universal Flash Memory (UFS) technology, allowing for higher bit density and larger storage capacity.
High-speed performance for demanding applications
With this new QLC UFS 4.0 device, Kioxia offers higher storage capacity in a compact structure, which is beneficial not only for compact devices such as mobile phones and tablets, but also for PCs, network systems, and AR, VR, etc. Emerging areas. AI Robust storage solutions are required.
Kioxia’s QLC UFS 4.0 device offers impressive data transfer rates, with 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 by utilizing the UFS 4.0 interface, which supports interface speeds up to 23.2 Gbps per channel or 46.4 Gbps per device.
The combination of QLC storage and the latest UFS interface technology provides significant performance improvements, making it ideal for data-intensive 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 its proprietary BiCS FLASH 3D flash memory, which is known for its durability and efficiency. Designed to meet JEDEC standards, the UFS 4.0 package combines this advanced memory with a dedicated controller to optimize performance. Kioxia’s UFS 4.0 device is backward compatible with UFS 3.1, providing users with an upgrade path.
To enhance its practical application, Kioxia’s QLC UFS 4.0 appliance adopts High-Speed Link Start Sequence (HS-LSS), a new method of accelerating device-to-host initialization. HS-LSS reduces link startup time by approximately 70% by allowing link startup at the faster HS-G1 Rate A instead of the traditional slower speed.
In addition to faster initialization, the device includes enhanced security features with advanced Replay Protected Memory Block (RPMB) functionality. These security measures protect user data by protecting access to sensitive information, such as credentials. With RPMB Purge, users can also ensure that discarded data is completely cleaned, adding another layer of confidence in data protection.
In addition, Kioxia’s QLC UFS Ver. 4.0 appliance supports extended initiator IDs (Ext-IIDs), which are designed for use with multi-cycle queues (MCQ) in UFS 4.0 host controllers. This feature improves random performance, a critical component for devices that require fast distributed access to data across multiple applications. With Ext-IID, the device can better manage complex data tasks and provide faster and more efficient performance for users with demanding workloads.
