In February 2015, JEDEC published the latest version of its popular e.MMC standard: JESD84-B51: Embedded MultiMediaCard (e.MMC), Electrical Standard (5.1).
e.MMC v5.1 defines new features and updates for this embedded mass-storage flash memory that is widely used in smartphones and other mobile devices. Intended to facilitate an enhanced end user experience, the new version of e.MMC offers command queueing for the first time, and also defines important security updates. JESD84-B51 is available for free download from the JEDEC website: http://www.jedec.org/standards-documents/results/jesd84-b51.
JESD84-B51 e.MMC v5.1 replaces all past versions of the e.MMC standard.

Designed for a wide range of applications in consumer electronics, mobile phones, handheld computers, navigational systems and other industrial uses, e.MMC is an embedded non-volatile memory system, comprised of both flash memory and a flash memory controller, which simplifies the application interface design and frees the host processor from low-level flash memory management. This benefits product developers by simplifying the non-volatile memory interface design and qualification process – resulting in a reduction in time-to-market as well as facilitating support for future flash device offerings. Small BGA package sizes and low power consumption make e.MMC a viable, low-cost memory solution for mobile and other space-constrained products.
