Abstract

Apparatus having an array of memory cells include a controller configured to read a particular memory cell of a last written page of memory cells of a block of memory cells of the array of memory cells, determine whether a threshold voltage of the particular memory cell is less than a particular voltage level, and mark the last written page of memory cells as affected by power loss during a programming operation of the last written page of memory cells when the threshold voltage of the particular memory cell is determined to be higher than the particular voltage level.
