Abstract: The present disclosure is drawn to, among other things, a method for programming a memory device comprising a plurality of memory arrays. The method may include receiving a command to program one or more of the plurality of memory arrays and programming the one or more of the plurality of memory arrays based on the command. The method may optionally include erasing the one or more of the plurality of memory arrays prior to the programming.

Abstract: The present disclosure is drawn to, among other things, a method of managing a memory device. In some aspects, the method includes determining whether a first address for a page in a first memory region is mapped in a map table, setting a target address as a second address identified in the map table as being mapped to the first address, setting the target address as the first address, determining a number of bits that fail in each word of a plurality of first-layer error correction code (ECC) words for the target address, and adding the target address to the map table, writing-back contents from the target address to a repair address in the first memory region, and updating the map table by mapping the target address to the repair address.
