Value blocks: fixed data format which permits native error detection and correction and a backup management.Ī value block can only be generated through a write operation in value block format:.Read/Write blocks: fully arbitrary data, in arbitrary format.The data blocks can be configured by the access conditions bits as: Data blocks: All sectors contain 3 blocks of 16 bytes for storing data (Sector 0 contains only two data blocks and the read-only manufacturer block).Manufacturer block: This is the first data block (block 0) of the first sector (sector 0).The last block of each sector is called “trailer”, which contains two secret keys and programmable access conditions for each block in this sector. Useful notes from MIFARE Classic 1K datasheet:ĮEPROM: 1 kB is organized in 16 sectors of 4 blocks.
