One-time programmable memory device and fault tolerance method thereof

A tolerance method for the one-time programmable memory, comprising:

• configuring a first block, a second block and a third block in a one-time programmable memory of a one-time programmable memory device;
• and
• controlling, by a memory controller of the one-time programmable memory device, the first block, the second block and the third block;
• wherein the first block comprises a plurality of initial-address-unit groups and each initial-address-unit group comprises a plurality of initial address units and wherein in each initial-address-unit group, each initial address unit corresponds to a corresponding variable and records encoded content associated with a storage address of associated with its corresponding variable;
• wherein the second block comprises a plurality of initial address control units and each initial address control unit corresponds to one of the variables, wherein each initial address control unit records encoded content associated with the corresponding initial-address-unit group associated with its corresponding variable;
• wherein the third block comprises a plurality of storage units, wherein each storage unit has a corresponding storage address and stores content of one variable associated with the corresponding storage address of the storage unit, and the memory controller is configured to assign the storage addresses to the variables;
• and
• wherein the number of variables is smaller than the number of storage units.
