UFS & e-MMC for Automotive

Paving the Road Ahead for the Automotive Applications of the Future

KIOXIA offers a broad density lineup of high-speed UFS and e-MMC memory for automotive applications, and is well positioned to support data storage demands of increasingly complex automotive applications. KIOXIA automotive UFS and e-MMC support a temperature range of -40°C to +105°C, meets AEC-Q100 Grade 2(8) requirements and offers extended reliability required by demanding automotive applications.

Automotive Functions Require Flash Storage

Next-gen automotive systems are hungry for more. More advanced infotainment and ADAS (advanced driver-assistance system). More storage for event data recording. Support for more 3D mapping. And hungry for entirely new applications and capabilities that take advantage of 5G, IoT and artificial intelligence.

Requirements of Automotive UFS & e-MMC

  • Compliant with IATF16949
  • 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., -40°C to +105°C)
  • Low Failure Rate
  • Extended Product Change Notices (PCNs)
  • Features for automotive (e.g., enhanced solder ball reliability, countermeasures if chip exceeds certain temp, etc.)

Automotive UFS(6)

Available capacities: 32GB, 64GB, 128GB, 256GB and 512GB.

Automotive e-MMC(7)

Available capacities: 8GB, 16GB, 32GB, 64GB, 128GB and 256GB.

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
  • Support for full duplexing

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.
