Abstract
A method for repairing a memory includes executing an Error Correction Code (ECC) for a page of the memory. The page includes a plurality of bits having an inherent number of failed bits equal to or greater than zero. The ECC is configured to correct a correctable number of failed bits from the plurality of bits. A location of a failure prone bit in the page is determined from a cache in response to the correctable number of failed bits being less than the inherent number of failed bits. A state of the failure prone bit is changed to a new state in response to determining the location of the failure prone bit. The ECC is executed in response to the state of the failure prone bit being changed to the new state.
