Claim:
1. A one-time programmable (OTP) memory, comprising: a programmable transistor having a first threshold voltage and a first breakdown voltage, the programmable transistor comprising a first source region, a first drain region, and a first gate electrode; a pass transistor having a second threshold voltage and a second breakdown voltage, the pass transistor comprising a second source region, a second drain region, and a second gate electrode; and a combined word line programming line (WL-PL) electrically connected to the first gate electrode and the second gate electrode, wherein the first source region is electrically connected to the second drain region and the second source region is electrically connected to a bit line, and wherein a first work function of the first gate electrode is less than a second work function of the second gate electrode.
