Abstract
To reduce the pre-programming cost, an efficient three-dimensional one-time-programmable read-only memory (3D-OTP) is disclosed. It comprises a dummy word line and a plurality of dummy bit lines. Only the dummy OTP cells at the intersections of the dummy word line and dummy bit lines are programmed. All other dummy OTP cells are unprogrammed.
