摘要:
A mask read-only memory (ROM) includes a dielectric layer formed on a substrate and a plurality of first conductive lines formed on the dielectric layer. A plurality of diodes are formed in the first conductive lines, and a plurality of final vias are formed for a first set of the diodes each representing a first type of memory cell, with no final via being formed for a second set of diodes each representing a second type of memory cell. Each of a plurality of second conductive lines is formed over a column of the diodes.
