Abstract
A method and system for detecting and correcting a bad bit error in a solid-state nonvolatile memory device. The device includes a bad bit detection module that receives an old page from the memory device and determines whether a page has a bad bit. The device further includes a bad bit correction module that generates a new page, determines a location of the bad bit, determines a preferred value of the bad bit, determines a user value of the bad bit and inserts the preferred value into a string of bits corresponding to substantive data of the old page, recording the string of bits with the preferred value inserted therein and stores the new page at an address of the old page.
