Abstract
A semiconductor device including at least an OTP unit cell is disclosed. The OTP unit cell includes a read select transistor, a data storage transistor serially connected to the read select transistor, and a program select transistor. The drain of the program select transistor is electrically coupled to the gate of the data storage transistor. The programming path for programming the three-transistor unit cell is different from the reading path for reading the OTP unit cell.
