One of the most crucial components in smartphones is undoubtedly the storage chip, and with UFS 4.0, the storage on phones has never been this fast, but there’s always room for improvement. The modern UFS chips perform as fast as an SSD, yet Kioxia has managed to make UFS 4.0 even faster.
Kioxia’s new UFS chips offer 50% faster random write in 18% smaller area
Kioxia, a company founded by Toshiba, specializes solely in storage and memory solutions. The chips introduced by Kioxia come with storage capacities of 256GB, 512GB, and 1TB. Kioxia unveiled the THGJFMT1E45BATV, THGJFMT2E46BATV, and THGJFMT3E86BATZ chips. We can say that Android phones packing just 128GB of storage are quickly becoming outdated, if they’re rocking UFS 4.0 tech for sure.
The dimensions of the 256GB and 512GB chips are 9.0 x 13.0 x 0.8mm, while the 1TB chip’s dimensions are 9.0 x 13.0 x 0.9mm. Kioxia equipped the new UFS 4.0 chips with BiCS Flash 3D NAND, making them 18% smaller compared to the previously introduced 11mm x 13mm chips.
The write speed of the new UFS chips has increased by 15%, and the random write speed has surged by a whopping 50%, also with a 30% increase in random read speed. However, the maximum read upper limit remains unchanged, capped at 4640MB/s. These speed improvements were based on comparison with Kioxia’s previously released 512GB chip (THGJFLT2E46BATP).
Kioxia announced that the production of the 256GB and 512GB variants of these new chips will commence this month, while the 1TB variant will start production in June.
