ABSTRACT:
A mask ROM includes bit lines, word lines intersecting with the bit lines and bit cells provided along the word lines, each of the bit lines being formed of a cell transistor having a gate connected to an associated one of the word lines. In the mask ROM, further provided is a source node commonly connected to respective sources of ones of the cell transistors having a gate connected to one of adjacent two word lines. A current flows from a selected bit line to a non-selected bit line via a cell transistor selected in reading out data and the source node.
