PURPOSE: A device and a method for controlling an interrupt are provided to disable the interrupt if an interrupt request is terminated by adding a logic automatically disabling each interrupt. CONSTITUTION: An interrupt delay tool(210) receives an interrupt request signal and a clock, and generates the first and the second delayed interrupt request signal according to the clock signal. An interrupt controller(220) receives the clock signal, the interrupt request signal, and the first and the second delayed interrupt request signal, enables an interrupt signal if a rising edge of the interrupt request signal is detected, and disables the interrupt signal if a falling edge of the interrupt request signal is detected.
