  • Voltage control method and voltage control circuit for anti-fuse memory array
    Patent number: 11848062
    Abstract: A voltage control method and a voltage control circuit for an anti-fuse memory array, including: obtaining a storage data address, dividing the storage data address into multiple subdata addresses, decoding each subdata address to obtain a corresponding group of decoder output signals, converting the corresponding group of decoder output signals into a group of control signals by a corresponding group of high voltage converters; connecting multiple groups of data selectors in series, outputting selection voltages input to each group of data selectors to an anti-fuse unit under the control of the corresponding group of control signals; programming or reading an anti-fuse unit; the selection voltages include one of a programming selection voltage, a reading selection voltage, and a non-designated selection voltage. The present disclosure reduces the number of transistors and saves layout areas when the programming or reading operation is performed.
