Abstract
A memory device includes an array comprising a plurality of one-time-programmable (OTP) memory cells; a plurality of word lines (WLs); a plurality of bit lines (BLs); and a plurality of control gate (CG) lines. Each of the OTP memory cells comprises a first fuse resistor, a second fuse resistor, a first transistor, and a second transistor. The first fuse resistor and the second fuse resistor are coupled to a corresponding one of the BLs, while the first transistor and the second transistor are gated by a first one and a second one of the CG lines, respectively.
