  • Patent number: 9362001
    Abstract: A memory cell includes a programming selection transistor, a following gate transistor, an antifuse element, and a reading circuit. A charging current formed by the antifuse element may trigger the reading circuit to form a stable read current during a reading operation of the memory cell so that the time for reading data from the memory cell can be shortened. A discharging process may be operated in the beginning of the reading operation of the memory cell so that the window of time for reading data from the memory cell can be widened.
