A one time programming (OTP) memory cell includes a first transistor and a second transistor. The first transistor has a first drain, a first source, a first gate, and a first normal operational voltage value higher that a second normal operational voltage value of the second transistor. The second transistor has a second drain, a second source, and a second gate. The first source is coupled to the second drain. The second source is configured to detect data stored in the OTP memory cell.
