Abstract:
A method and apparatus for managing memory in an electronic system is described. The method includes determining a failure in an element of the memory array that is repairable by a redundant element. The method may further include using a latch to identify the redundant element. The method may also include that upon an event, using a value in the latch in an eFuse which subsequently selects the redundant element.
