ICODE 3 (TagTamper)

8.2 Memory organization

The 2432-bit user-accessible EEPROM memory is divided into 76 blocks. The block is the smallest access unit.

Each block consists of 4 bytes or 32 bits. Bit 0 in each byte represents the least significant bit (LSB) and bit 7 is

the most significant bit (MSB).

The entire memory is divided into two parts:

• User memory

– The blocks 0 to 74 (2400 bits) are used to store the user data. Direct read/write access to this part of the

memory is possible depending on the security and write protection conditions. The user memory can be

accessed with the READ and WRITE commands.

– The last block of the user memory (block 75) contains the 24-bit counter and the password protection flag of

the counter.

• Configuration memory

– This part of the memory stores the information to configure the ICODE 3. The configuration memory can be

accessed with the READ CONFIG and WRITE CONFIG commands.

Note: Block 75 contains the 24-bit counter and cannot be used to store user data. READ and WRITE

commands to that block require special data considerations (refer to Section 8.5.3.25).
