Kioxia Corporation, a global leader in storage solutions, announced today that it has begun offering new Universal Flash Storage (UFS) 4.1 version embedded storage device samples, further consolidating its leading position in high-performance storage. These new devices are designed to meet the needs of the next generation of mobile applications, including advanced smartphones equipped with device side AI, which achieve performance improvements and higher energy efficiency in small BGA packages (3).
Kioxia's UFS 4.1 version device integrates the company's innovative BiCS FLASH in the JEDEC standard package ™ 3D flash memory and controller. These new UFS devices use Kioxia's 8th generation BiCS FLASH ™ 3D flash memory (1) creation. This generation of products introduces CBA (CMOS direct bonding array) technology - an architectural innovation that marks a significant leap in flash memory design. By directly bonding CMOS circuits to storage arrays, CBA technology significantly improves energy efficiency, performance, and storage density.
Kioxia's UFS 4.1 version device combines high-speed and low-power characteristics, aiming to enhance user experience, achieve faster download speeds, and smoother application performance.
The core features include:
• Provides three capacity options: 256 GB, 512 GB, and 1 TB
• Improved performance compared to the previous generation product (3):
Random write: The 512 GB/1 TB version increases by about 30%
Random read: The 512 GB version increases by about 45%, and the 1 TB version increases by about 35%
• Improved energy efficiency compared to the previous generation product (3):
• Read: The 512 GB/1 TB version has increased by approximately 15%
• Write: Approximately 20% increase in 512 GB/1 TB version
• Support host initiated fragmentation function, which can delay garbage collection and ensure sustained high-speed performance in critical scenarios
The WriteBooster buffer can be resized to provide higher flexibility for optimizing performance
• Complies with UFS version 4.1 standards
The packaging height of the 1 TB model has been reduced compared to the previous generation product (4)
• Adopting Kioxia 8th generation BiCS FLASH ™ 3D flash memory (1)
