Original Abstract Submitted
A memory device includes a plurality of one-time-programmable (OTP) memory cells formed as a memory array. Each of the plurality of OTP memory cells includes a transistor and a metal structure electrically coupled to each other in series, and the plurality of OTP memory cells are formed on a first side of a substrate. The memory device includes a heater structure, disposed on a second side of the substrate opposite to the first side, that includes a plurality of interconnect structures. The plurality of interconnect structures are configured to conduct a substantially high current so as to elevate a temperature of the resistor when any of the OTP memory cells is being programmed.
