Introduction to eMMC Technology

1 What is eMMC eMMC stands for embedded MultiMediaCard, which is a standard for flash memory cards that defines the physical architecture and access interface and protocol for storage systems based on embedded MultiMediaCard, specifically established and published by the JEDEC (Joint Electron Device Engineering Council).It is an extension of MMC with advantages such as … Read more

Super Positioning Without Locator Frame for eMMC Sockets

Super Positioning Without Locator Frame for eMMC Sockets

The socket comes in two versions, both offering the same functionality. The framed version requires manual swapping of the locator frame when encountering chips of different sizes; the frame-less version directly utilizes solder balls and base positioning holes, eliminating the frame-swapping step. Super positioning without a locator frame: for chips of different sizes, positioning is … Read more
