Abstract:
The present invention discloses a multi-bit-per-cell three-dimensional read-only memory (3D-OTP MB ) comprising a plurality of dummy bit lines. It comprises a plurality of OTP cells stacked above a semiconductor substrate. Each OTP array comprises at least four dummy bit lines.

Claim (Index 1):
A multi-bit-per-cell three-dimensional read-only memory (3D-OTP MB ), comprising:\n a semiconductor substrate including transistors thereon; an OTP array stacked above said semiconductor substrate, said OTP array comprising a plurality of OTP cells including a first unprogrammed dummy OTP cell and a second programmed dummy OTP cell, each of said OTP cells comprising an antifuse layer; a first dummy bit line associated with said first unprogrammed dummy OTP cell; a second dummy bit line associated with said second programmed dummy OTP cell; a third dummy bit line associated with a third programmed dummy OTP cell, said second and third dummy OTP cells having a same state; a fourth dummy bit line associated with a fourth programmed dummy OTP cell, said second and fourth dummy OTP cells having different states; a plurality of contact vias coupling said OTP cells to said semiconductor substrate; a first differential amplifier with a first input disposed on said semiconductor substrate, wherein said first input is coupled with said first and second dummy bit lines; a second differential amplifier with a second input disposed on said semiconductor substrate, wherein said second input is coupled with said third and fourth dummy bit lines; wherein said OTP cells have more than two states, the OTP cell in different states being programmed by different programming currents.
