== Cartes MiFare Ultralight ==
MiFare Ultralight cards typically contain 512 bits (64 bytes) of memory, including 4 bytes (32-bits) of OTP (One Time Programmable) memory where the individual bits can be written but not erased.
* [http://www.nxp.com/documents/data_sheet/MF0ICU1.pdf MF0ICU1 MiFare Ultralight Functional Specification] (''pdf, NXP'')
MiFare Ultralight cards have a 7-byte UID that uniquely identifies the card.
=== Mémoire EEPROM ===
MiFare Ultralight cards have 512 bits (64 bytes) of EEPROM memory, including 4 byte (32 bits) of OTP memory. Unlike Mifare Classic cards, there is no authentication on a per block level, although the blocks can be set to "read-only" mode using Lock Bytes (described below).
EEPROM memory is organised into 16 pages of four bytes eachs, in the following order:
<nowiki> Page Description
---- ------------
0 Serial Number (4 bytes)
1 Serial Number (4 bytes)
2 Byte 0: Serial Number
Byte 1: Internal Memory
Byte 2..3: lock bytes
3 One-time programmable memory (4 bytes)
4..15 User memory (4 bytes)</nowiki>
Here are the pages and blocks arranged in table format:
<nowiki> Page Block 0 Block 1 Block 2 Block 3
----- ---------------------------------------
0 [ Serial Number ]
1 [ Serial Number ]
2 [Serial] - [Intern] - [ Lock Bytes ]
3 [ One Time Programmable Memory ]
