ABSTRACT:
A programmable ROM device comprising, for example, junction-shorting-type or fuse-blown-type memory cells, connected between word lines and bit lines, in which device information is written into a selected memory cell by applying a high voltage to a terminal such as a CE terminal and by applying a write-in current to the bit line connected to the selected memory cell and in which leakage of the write-in current into memory cells adjacent to the selected memory cell is prevented, thereby providing a reliable information-storing operation.
