Abstract
A semiconductor nonvolatile memory device according to the invention comprises a first cell block having with a current path and a plurality of memory cells, a second cell block having with a current path and a plurality of memory cells, the current path of the second cell block has an end connected to a corresponding end of the current path of the first cell block, a first line electrically connected to the other end of the current path of the first cell block, and a second line electrically connected to the other end of the current path of the second cell block. The first and second lines are made to operate a bit line and a source line, or vise versa, depending on which one of said cell blocks is selected for data retrieval.
