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 We can say that Android phones packing just 128GB of storage are quickly becoming outdated, if they’re rocking UFS 4.0 tech for sure.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.

As the United States imposed new sanctions on Chinese giant Huawei, more and more companies are facing the heat. With new restrictions, Japan-based companies that supply chips to Huawei, are facing the risk of losing billions of dollars in revenue.

Now, as per the latest report, in order to avoid losing money, Japanese companies Sony and Kioxia have applied for approval from the United States to continue doing business with Huawei. It’s noteworthy that Intel has already been granted a license to supply chipsets to the Chinese giant.

Huawei is one of the top buyers of image sensors from Sony while Kioxia is one of the world’s leading flash memory chip makers and is also a major supplier to the Chinese telecom giant, which was also the leading smartphone brand in Q2 2020.

Since the U.S. government added new sanctions on the Chinese giant, Sony trimmed its capital spending plan for three years, as there’s now a gap of billions of dollars in sales from supplying image sensors to Huawei.

On the other hand, Kioxia, which is a Toshiba spinoff, has warned that restricting supply to Huawei could trigger memory chip oversupply and thus lower the prices. Because of the uncertainty, the company has shelved its plan for a multi-billion dollar listing.

However, these Japanese companies are not the only ones in line to get a license from the U.S. South Korean companies like Samsung Electronics and SK Hynix have also applied to get a green signal to continue supplying components to Huawei.
