OEMs use the manufacturing date (MDT) and serial number (PSN) from the CID to track warranty status. A decoder quickly tells you if a chip is still under warranty.
Here is a simplified breakdown of the CID fields as defined by the JEDEC standard:
The upper 4 bits signify the major revision, and the lower 4 bits represent the minor revision. 0x01 translates to hardware revision 0.1 . emmc cid decoder
eMMC (embedded MultiMediaCard) is a type of flash storage that is widely used in mobile devices, such as smartphones, tablets, and laptops. It is a small, low-power, and low-cost storage solution that provides fast data transfer rates and high storage capacity. eMMC is designed to provide a high level of performance, reliability, and security, making it an ideal storage solution for mobile devices.

# Byte 15: CRC (CRC) crc_byte = raw_bytes[15]
The process of obtaining and decoding a raw CID value can be accomplished using a variety of software tools and system methods. The following table provides a quick reference for the most common approaches across different operating systems: 0x01 translates to hardware revision 0
Bits 111 down to 64 span 6 bytes (12 hex characters). Decoders convert these hex values directly into standard ASCII text characters. For example, the hex sequence 4d4147324741 translates directly to the ASCII string , which is a known Samsung eMMC model name. 3. Decoding the Product Revision (PRV)
For those performing "eMMC Pro" or "EasyJTAG" repairs, knowing the exact manufacturing date and revision can help in selecting the correct firmware (dump) to flash onto a bricked device.
