Memory mapping
The LRI64 is organized as 15 blocks of 8 bits as shown in
automatically write-protected after the first valid write access.
Figure 3.
The LRI64 uses the first 8 blocks (blocks 0 to 7) to store the 64-bit unique identifier (UID).
The UID is used during the anticollision sequence (Inventory). It is written, by ST, at time of
manufacture, but part of it can be customer-accessible and customer-writable, on special
request.
The LRI64 has an AFI register, in which to store the application family identifier value, which
is also used during the anticollision sequence.
The LRI64 has a DSFID register, in which to store the data storage format identifier value,
which is used for the LRI64 Inventory answer.
The five following blocks (blocks 10 to 14) are write-once read-many (WORM) memory. It is
possible to write to each of them once. After the first valid write access, the block is
automatically locked, and only read commands are possible.
