ABSTRACT:
A method for performing multi-programmable function with one-time programmable (OTP) memories includes: generating a newest word in a OTP memory array; receive a word-to-be-record; comparing the newest word and the word-to-be-record; and according to a result, recording bit information between the newest word and the word-to-be-record into the OTP memory array. Therefore the method and apparatus can simplify hardware circuit and reduce production costs of additional memory units, furthermore the memory count is not limited to only OTP memory block count.
