Abstract
A one-time programmable (OTP) memory cell is disclosed, which comprises an electric fuse structure, an anti-fuse transistor and a word select transistor. One end of the electric fuse structure is electrically connected to a gate of the anti-fuse transistor to form a first port of the OTP memory cell, the other end of the electric fuse structure is electrically connected to a source of the anti-fuse transistor and is connected to a drain of the word select transistor, and a gate and a source of the word select transistor form a second port and a third port of the OTP memory cell respectively. The operation method of the OTP memory cell has the capability of one-time correction, expanding the practicability of the OTP memory cell.
