Abstract:
A nonvolatile semiconductor memory device comprises a cell array including a plurality of first lines, a plurality of second lines intersecting the plurality of first lines, and a plurality of memory cells arranged in matrix and connected at intersections of the first and second lines between both lines, each memory cell containing a serial circuit of an electrically erasable programmable variable resistive element of which resistance is nonvolatilely stored as data and a non-ohmic element; and a plurality of access circuits operative to simultaneously access the memory cells physically separated from each other in the cell array.
