Abstract
A method of storing repair data of a memory array in a one-time programming memory (OTPM) includes performing a first test and repair of the memory array using a built-in self-test-and-repair (BISTR) module to determine first repair data. The method includes loading the first repair data in a repair memory and in a duplicated repair memory of the BISTR module. The method includes performing a second test and repair to determine second repair data. The method includes storing the second repair data in the repair memory of the BISTR module and in the repair memory of the memory array. The method includes processing the repair data in the repair memory and the duplicated repair memory of the BISTR module. The method includes storing the output of the logic gate in the repair memory of the memory array. The method includes storing content of the repair memory in the OTPM.
