Automotive UFS

Our broad density lineup of high-speed UFS memory for automotive applications is perfectly positioned to support the data storage demands of increasingly complex automotive applications.

KIOXIA Automotive UFS supports a wide temperature range (-40°C to +105°C), meets AEC-Q100 Grade 2 requirements and offers the extended reliability required by various automotive applications. Available capacities include 16GB, 32GB, 64GB, 128GB, 256GB and 512GB.

Automotive e-MMC

As with KIOXIA’s Automotive UFS, our Automotive e-MMC supports a wide temperature rage (up to 105°C), meets AEC-Q100 Grade 2 requirements, and features the enhanced reliability that automotive applications demand.

Changing Lanes

UFS was specifically developed to be the high-performance replacement to e-MMC. Market demand for UFS will eventually surpass e-MMC, though e-MMC will continue to be an option for applications requiring lower densities.

  • UFS is the faster performance JEDEC standard replacement to e-MMC
  • UFS is replacing e-MMC in Smartphones and other markets and migrating into Automotive

Why UFS?

Simply put – it’s the ideal successor to e-MMC. UFS performance will continue to advance, widening the already significant performance advantage it has over e-MMC.

When compared to e-MMC, UFS delivers:

  • A faster interface
  • Higher performance for reads and writes
  • Higher density offerings
  • Better power efficiency
  • Support for full duplexing

Additional Features well-suited for Automotive Reliability

  • Thermal Control: If the device exceeds 105C, the device notifies the host processor to take action
  • Extended Diagnosis: UFS controller monitors various items such as w/e cycles, current temperature, etc. and reports device status to the host processor
  • Better long term support in the market: UFS is now the main storage for the large mobile market, as is being adopted by automotive

Auto Requirements

  • Meets Automotive standards (e.g., AEC-Q100 Stress Test Qual Standard)
  • Supports PPAP (to ensure consistent production of quality parts)
  • Extended Temperature Range (e.g., -40C to +105C)
  • Low Failure Rate
  • Extended PCNs
  • Longevity of Support
  • Features ideal for Automotive (e.g., enhanced solder ball reliability, countermeasures if chip exceeds certain temp, etc.)

KIOXIA has led the way in UFS since 2013, when we were the first to sample the technology, and will continue to pave the road forward for the automotive applications of the future.
