Abstract
The memory device includes a plurality of programmed memory blocks containing data and at least one spare memory block that does not contain data. The memory device also includes control circuitry that is configured to perform a plurality of read operations on the programmed memory blocks. Without having reprogrammed the memory cells of any of the plurality of programmed memory blocks, the circuitry is configured to detect a trigger event. In response to detecting the trigger event, the circuitry is configured to relocate data from a selected memory block of the plurality of programmed memory blocks to the at least one spare memory block so that the at least one spare memory block becomes a programmed memory block and then erase the selected memory block so that the selected memory block becomes a new spare memory block.
