Abstract:
The present invention discloses a three-dimensional vertical read-only memory ( 3 D-OTP V ) comprising no separate diode layer. It comprises a plurality of vertical address line, a plurality of memory holes through said vertical address line, a plurality of antifuse layers and vertical address lines in said memory holes. The memory holes comprise no separate diode layer. The horizontal and vertical address lines comprise different metallic materials.

Claim (Index 1):
A three-dimensional vertical read-only memory (3D-OTP V ), comprising:\n a semiconductor substrate comprising a substrate circuit; a plurality of vertically stacked horizontal address lines above said semiconductor circuit, said horizontal address lines comprising a first metallic material; at least a memory hole through said plurality of horizontal address lines; an antifuse layer formed on the sidewall of said memory hole, wherein said antifuse layer is irreversibly switched from a high-resistance state to a low-resistance state during programming; a vertical address line formed by filling at least a conductive material in said memory hole, said vertical address lines comprising a second metallic material; a plurality of OTP cells formed at the intersections of said horizontal address lines and said vertical address line; said first and second metallic materials are different metallic materials.
