Kioxia introduces UFS Ver. 4.0 flash memory devices, revolutionizing embedded storage.

Kioxia Corporation, a global leader in memory solutions, has announced the commencement of sampling for its latest generation of Universal Flash Storage (UFS) Ver. 4.0 embedded flash memory devices. These products, available in capacities of 256GB, 512GB, and 1TB, are specifically designed to meet the demands of next-generation mobile applications, including high-end smartphones. With improved performance, these UFS devices optimize the utilization of 5G connectivity, resulting in faster downloads, reduced Latency, and an overall enhanced user experience. Furthermore, the smaller package size contributes to increased board space efficiency and design flexibility.

Kioxia has been at the forefront of UFS technology and continues to push boundaries with its innovative product development. The latest UFS Ver. 4.0 devices combine the company’s BiCS FLASH 3D flash memory with a controller in a JEDEC-standard package. Leveraging MIPI M-PHY 5.0 and UniPro 2.0, UFS 4.0 supports theoretical interface speeds of up to 23.2 gigabits per second (Gbps) per lane or 46.4 Gbps per device. It’s worth noting that UFS 4.0 maintains backward compatibility with UFS 3.1, ensuring seamless integration with existing systems.

Key features of the new UFS Ver. 4.0 devices include significant improvements in read/write speeds compared to the previous generation: approximately 15% sequential write, 50% random write, and 30% random read speed enhancements. Additionally, there is a reduction in package size when compared to its predecessor, with dimensions of 9mm x 13mm and a thickness of 0.8mm for the 256GB and 512GB variants, and 0.9mm for the 1TB variant. This represents an approximate 18% reduction in size compared to conventional package dimensions of 11mm x 13mm.

Latency: Technology latency is the time it takes for a computer system to respond to a request. It is an important factor in the performance of computer systems, as it affects the speed and efficiency of data processing. In the computer industry, latency is a major factor in the performance of computer networks, storage systems, and other computer systems. Low latency is essential for applications that require fast response times, such as online gaming, streaming media, and real-time data processing. High latency can cause delays in data processing, resulting in slow response times and poor performance. To reduce latency, computer systems use various techniques such as caching, load balancing, and parallel processing. By reducing latency, computer systems can provide faster response times and improved performance.
