摘要： A read-only memory includes a semiconductor substrate; a memory cell matrix which is formed on the semiconductor substrate; and word and bit lines which define the locations of the memory cell matrix. The memory cell matrix includes field effect transistors, each of which turns off when accessed or addressed; and conducting regions, which keep conductive state all the time. Binary data stored in the memory cell matrix are determined by detecting current flowing through the selected bit line.
