ABSTRACT:
A semiconductor storage device includes a plurality of memory cells connected to first and second column trees, and a sensing circuit reading data from the memory cells. The sensing circuit performing a read operation by electrically connecting the column tree, which is connected to a read-selected memory cell, to a sensing node and electrically connecting the column tree, which is connected to a non-selected memory cell, to a reference sensing line.
