ABSTRACT:
A silicon-on-insulator (SOI) Read Only Memory (ROM), and a method of making the SOI ROM. ROM cells are located at the intersections of stripes in the surface SOI layer with orthogonally oriented wires on a conductor layer. Contacts from the wires connect to ROM cell diodes in the upper surface of the stripes. ROM cell personalization is the presence or absence of a diode and/or contact.
