PROGRAMMABLE MEMORY AND ACCESS METHOD FOR THE SAME

A programmable memory includes N number of one-time programmable (OTP) memory rows, an output module, a judge module, and a write-in module. The output module receives all data of the OTP memory rows and generates output data. The judge module receives the output data and write-in data and generates write-in control data according to the output data and the write-in data. When a bit datum of the output data is different to a bit datum of the write-in data, the bit of the write-in control data is enabled. The write-in module receives the write-in control data and stores a preset bit datum in an unprogrammed OTP memory cell of an OTP memory row corresponding to the enabled bit.
