Abstract
Various one-time-programmable (OTP) memory cells are disclosed. An OTP memory cell includes an additional dopant region that extends at least partially under the gate of a transistor, such as an anti-fuse transistor. The additional dopant region provides an additional current path for a read current. Alternatively, an OTP memory cell includes three transistors; an anti-fuse transistor and two select transistors. The two select transistors can be configured as a cascaded select transistor or as two separate select transistors.
