Abstract
A semiconductor device includes at least a one-time programmable (OTP) physically unclonable function (PUF) unit cell with the PUF unit cell coupled to a bit line and a source line and includes an encode transistor is proposed. An encode enable transistor directly couples the bit line and the source line. A path programming the encode transistor is different from a path reading the encode transistor.
