Claim 15:
16. A system, comprising:
a memory device configured to store data, the memory device comprising:
an array of memory cells in a plurality of memory strings and arranged in a plurality of rows of memory cells;
a plurality of word lines respectively coupled to the plurality of rows of memory cells; and
