The enhanced performance4 of the new UFS products provides
optimal utilization of 5G connectivity, resulting in accelerated
downloads, minimized latency, and an enhanced user experience. A
smaller package4 size contributes to board space efficiency and
design flexibility.
KIOXIA was the first to introduce UFS technology5, and continues
to develop new products. The latest UFS Ver. 4.0 devices
integrate the company’s innovative BiCS FLASH™ 3D flash memory and
a controller in a JEDEC standard package. UFS 4.0 incorporates
MIPI® M-PHY® 5.0 and UniPro® 2.0 and supports theoretical interface
speeds of up to 23.2 gigabits per second (Gbps) per lane or 46.4
Gbps per device. UFS 4.0 is backward compatible with UFS 3.1.
Key Features include:
- Read/write speed improvement over previous generation6: +15%
sequential write, +50% random write and +30% random read.
- Package size reduction over previous generation6: Package size
is 9x13 and package thickness is 0.8mm (256GB and 512GB) and 0.9mm
(1TB), resulting in an 18% reduction compared to the conventional
package size (11x13).
Maitry Dholakia, vice president, Memory Business Unit, for
KIOXIA America, Inc. emphasized the company's ongoing leadership in
UFS technology, stating, "The newest generation of our UFS 4.0
devices is a testament to our commitment to continually push
performance boundaries – and make an improved user experience a
reality."

FOOTNOTES:
1: Sample shipments will begin this month. Specification of the
samples may differ from commercial products.
2: Universal Flash Storage (UFS) is a product category for a
class of embedded memory products built to the JEDEC UFS standard
specification. Due to its serial interface, UFS supports full
duplexing, which enables both concurrent reading and writing
between the host processor and UFS device.
3: In every mention of a KIOXIA product: Product density is
identified based on the density of memory chip(s) within the
Product, not the amount of memory capacity available for data
storage by the end user. Consumer-usable capacity will be less due
to overhead data areas, formatting, bad blocks, and other
constraints, and may also vary based on the host device and
application. For details, please refer to applicable product
specifications. The definition of 1KB = 2^10 bytes = 1,024 bytes.
The definition of 1Gb = 2^30 bits = 1,073,741,824 bits. The
definition of 1GB = 2^30 bytes = 1,073,741,824 bytes. 1Tb = 2^40
bits = 1,099,511,627,776 bits.
4: Compared to previous generation.

Read and write speeds are the best values obtained in a specific
test environment at KIOXIA and KIOXIA warrants neither read nor
write speeds in individual devices. Read and write speed may vary
depending on device used and file size read or written.
