As the market continues to shift to UFS⁴, there are cases where e-MMC may still be used. This includes consumer products with mid-range storage requirements such as tablets, personal computers, point of sale devices and other portable handheld devices, as well as Smart TVs and Smart NICs (Network Interface Card). KIOXIA continues to reinforce its market-leading position by delivering a broad, high-performance product lineup and expanding the available options for these applications.

The new KIOXIA e-MMC devices improve sequential and random write performance by 2.5x and random read performance by 2.7x over previous generation devices⁵*. Additionally, terabytes written (TBW)⁶ is improved by 3.3x over previous generation devices⁵*, in correspondence with an enhanced area setting⁷ for the whole e-MMC area.

As a leading provider of flash memory and storage for consumer applications and mobile devices, KIOXIA has been supporting e-MMC since 2007 and was the first supplier to introduce the higher performance follow-on solution to e-MMC, UFS, on February 7, 2013.

“e-MMC remains a popular embedded memory solution for a wide range of applications,” said Maitry Dholakia, vice president, Memory Business Unit, for KIOXIA America, Inc. “KIOXIA remains steadfast in its commitment to delivering the latest in flash technology for these applications. Our new generation brings new performance features which address end user demands – and create a better user experience.”

KIOXIA is now sampling its next-gen e-MMC devices, with mass production expected in 2024.

Notes:

[1]: The company’s newest devices are supported in two capacities: 64 gigabytes (GB) and 128GB. Sample shipments of the 64GB device began this month, with the 128GB device scheduled to follow after October. Specification of the samples may differ from commercial products.

[2]: Compared to previous generation devices.

[3]: e-MMC (embedded Multi Media Card): One of the standard specifications of embedded flash memory defined by JEDEC. The new product supports the command queuing and secure write protection functions which is specified as an option in JEDEC Ver. 5.1.

[4]: 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.

[5]: Compared to KIOXIA previous generation devices "THGAMSG9T24BAIL", "THGAMST0T24BAIL".

[6]: TBW or Terabytes Written measures how many cumulative writes that a drive can expect to complete over its lifespan.

[7]: If Enhanced Area is set, the total configurable user space will be reduced.

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

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.
