Global Standards for the Microelectronics Industry
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.
