摘要:
A method is for testing a non-volatile memory. A base data pattern is defined for a first pageset of the non-volatile memory. The non-volatile memory has a plurality of pages which comprise words. The base pattern is arranged so that each bitpair of a plurality of bitpairs that includes one of a group consisting of even bitpairs and odd bitpairs formed from all of the words exhibits all possible bitpair transitions during sequential accesses of the pages of the plurality of pages. The base pattern is stored in the first pageset. The pages of the plurality of pages of the first pageset are accessed sequentially.
