KIOXIA Europe GmbH announces sampling[1] of new, higher performing JEDEC e-MMC Ver. 5.1[2] compliant embedded flash memory products for consumer applications. The new products integrate the latest version of the company’s BiCS FLASH 3D flash memory[3] and a controller in a single package, reducing processor workload and improving ease of use. Both 64 and 128 gigabytes (GB) products will be available.
As the market continues to shift to UFS[4], 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.
The new KIOXIA devices improve sequential and random write performance by approximately 2.5x and random read performance by approximately 2.7x over previous generation devices[3]. Additionally, terabytes written (TBW)[5] is improved by approximately 3.3x over previous generation devices, in correspondence with an enhanced area setting[6] for whole e-MMC area.
[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]: e-MMC(embedded Multi Media Card): One of 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 [3]: Compared with KIOXIA’s previous generation devices THGAMSG9T24BAIL, “THGAMST0T24BAIL. [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]: TBW or Terabytes Written measures how many cumulative writes that a drive can expect to complete over its lifespan [6]: If Enhanced Area is set, the total configurable consumer-usable capacity will be reduced
