Next Generation UFS 4.0 for Automotive
KIOXIA UFS 4.0 automotive devices deliver enhanced capabilities to support increasingly sophisticated automotive applications. With an interface speed of up to 46.4Gbps and a range of density options, the new UFS 4.0 automotive devices are well-suited to support the next generation of complex automotive applications.
The Changing Interface from e-MMC (parallel) to UFS (serial)
UFS was specifically defined by JEDEC to be the high-performance memory replacement for e-MMC. It has become the premiere solution for smartphones, continuing to migrate into automotive and other applications. UFS will ultimately surpass e-MMC as the primary storage solution for automotive applications.
UFS Market Trend
UFS is the faster performance JEDEC standard replacement to e-MMC. Smartphone adopted UFS for its performance advantages. Automotive is doing the same.
Why UFS?
Simply put – it’s the successor to e-MMC. UFS performance will continue to advance, significantly widening its performance advantage over e-MMC.
Compared to e-MMC, UFS Delivers:
- A faster interface
- Higher performance for reads and writes
- Higher density offerings
- Better power efficiency
Boot Time Comparison (64MB Data-out)
Faster boot time with a large amount of boot data is a big motivation to use UFS in automotive applications.
UFS has a faster boot time than other storage devices thanks to its high speed sequential read.
Additional Automotive UFS Features Well-Suited for Automotive Reliability
- Thermal Control: If the device exceeds 105°C, the device slows the performance and notifies the host processor to take action
- Extended Diagnosis: the UFS controller monitors various items, such as write/erase cycles, current temperature, etc. and reports device status to the host processor
- Refresh: enables refresh of deteriorated data, improving data reliability.
KIOXIA has led the way in UFS since 2013, being first to sample the technology*,
and will continue to pave the road ahead for automotive applications of the future.

In 2007, KIOXIA announced the world‘s first 3D flash memory technology. Presenting our cutting-edge technologies, along with the key points of innovation and our efforts toward further increases in capacity.
KIOXIA invented the world’s first NAND flash memory in 1987. This is an explanation of the structure of flash memory and the mechanism of data storage.
“Multi-level cell technology” is one of the main technologies realizing larger capacity flash memory. The 1 Gbit MLC NAND flash memory launched by KIOXIA in 2001 was the first application in the world of multi-level cell technology to a NAND flash memory product.
