Patent ID: 7428474

Claim:
An integrated circuit (IC) with a self-proofreading function, comprising: a micro control unit (MCU); a one-time programmable (OTP) memory directly connected with the MCU; an electrical charge pump having an output port and an enable port connected to the MCU; and a switching circuit having a control port connected to the MCU; a first input port connected to the output port of the electrical charge pump, a second input port connected to a power source of the MCU, and an output port connected to the OTP memory to provide an operating voltage and a recording voltage for the OTP memory wherein the OTP memory comprises in instruction memory region for storing instructions, and a parameter memory region for storing standard parameters for proofreading, and wherein the instructions stored in the OTP memory has proofreading instructions and measuring instructions for enabling the IC operate under a proofreading mode and a measuring mode, respectively.
