ABSTRACT:
An integrated circuit is provided. The integrated circuit includes a memory device and a discharge circuit. The discharge circuit discharges the well voltage line and the first voltage line of the memory device after the end of the erasing period and includes a first and second switch circuit and a first and second control voltage supplier. The first switch circuit is coupled between the well voltage line, the first voltage line and a second supplier. The second switch circuit is coupled between the first switch circuit and a reference voltage. The first control voltage supplier is coupled to the first switch circuit and supplies a first control voltage to turn on the first switch circuit during a first discharge period. The second control voltage supplier is coupled to the second switch circuit, and supplies a second control voltage to turn on the second switch circuit during a second discharge period.
