A method and apparatus for testing correct operation of a page decoder in a memory is provided. In one implementation, the method includes erasing the memory to reset all memory cells associated with each of the N pages in the memory, and iteratively generating a unique bit sequence of M bits and programming the unique bit sequence into a plurality of the N pages at a given time until each of the N pages contains a unique bit sequence relative to other pages in the memory. Responsive to each of the N pages having a unique bit sequence, the method further includes using the page decoder to read out each unique bit sequence associated with the N pages to verify correct operation of the page decoder.
