One embodiment of the present invention capable of decommissioning a defective non-volatile memory (“NVM”) page in a block is disclosed. A process able to logically decommission a defective page is able to detect defective or bad pages while executing a write operation writing information to one or more NVM page in a NVM block. For example, after examining operation status after completion of the write operation, the NVM page is identified as a defective page if the operation status fails to meet a set of predefined conditions under a normal write operation. Upon marking a location of a page status table to indicate the NVM page as defective page, the page status table containing the page defective information associated with the NVM page is stored at a predefined page in the NVM block.
