Abstract
A flash memory has erase blocks aligned primarily with array rows and secondarily with array rows. This architecture allows data to be stored across numerous pages without risking accidental erasure caused by crossing multiple erase blocks. As a result, non-volatile memory devices to be more easily substituted for volatile memory devices. In one embodiment, a flash memory includes an array of memory cells that have a plurality of adjacent pages. Addresses of the memory cells are scrambled within the pages to define erase blocks that cross the page boundaries.
