Ever wondered exactly which eMMC chip is soldered to your single-board computer, smartphone, or embedded device? You can’t just run lshw or look at a sticker. But there’s a hidden fingerprint inside every eMMC: the .
This feature is essential for hardware developers, forensics experts, and repair technicians to verify the authenticity, age, and manufacturer of the storage silicon used in smartphones and IoT devices. Core Functionality emmc cid decoder
Decoding an eMMC CID (Card Identification) register allows you to extract manufacturer details, product revisions, and production dates from the 128-bit hexadecimal string stored in the chip. Online Decoders Ever wondered exactly which eMMC chip is soldered
A 6-character ASCII string representing the model name (e.g., "MAG2GA" or "KLMAG4"). This feature is essential for hardware developers, forensics
The CID is a unique, 16-byte read-only register embedded in every eMMC (embedded MultiMediaCard) chip. It serves as a digital "birth certificate" for the storage device. Manufacturer ID (MID): A 1-byte code assigned by the SD Association for Samsung, for Micron). OEM/Application ID (OID):
def decode_emmc_cid(cid_hex): # 1. Pre-processing cid_hex = cid_hex.strip().replace(" ", "").replace("0x", "").upper()
: If the eMMC is connected via a native MMC host interface, you can find the raw CID at /sys/block/mmcblkX/device/cid Hardware Tools : Professional repair tools like the Easy JTAG Plus Box
