Abstract
A programmable system for storage of one-time programmable information comprises an interface translator and a one-time programmable device. The interface translator receives and translates a command code to program code comprising a sequence of write instructions and a designated data block. The one-time programmable device is coupled to the interface translator, programmed by the write instructions to store the designated data block. The one-time programmable device can only be programmed once, such that the designated data block being stored is fully protected.
Claims18
A programmable system for storage of one-time programmable information, comprising:
- an interface translator, receiving and translating a command code to program code comprising a sequence of write instructions and a designated data block;
- a one-time programmable device, coupled to the interface translator, programmed by the write instructions to store the designated data block;
- wherein the one-time programmable device can only be programmed once.
A copy protection method for storage of one-time programmable information in a programmable system, wherein the programmable system comprises:
- an interface translator;
- a one-time programmable device, coupled to the interface translator;
- and
- the copy protection method comprises:
- the interface translator receiving and translating a command code to program code comprising a sequence of write instructions and a designated data block;
- and
- the one-time programmable device executing the write instructions to store the designated data block;
- wherein the one-time programmable device can only be programmed once, such that the designated data block being stored is fully protected.
