A device for dualizing main processors in an ATM switch and a method therefor. The device for dualizing main processors in an asynchronous transfer mode switch, including: dualization controllers, each of which is in an active mode and a standby mode and connected s with memories of each of corresponding modes by way of an MBS, each of the dualization controller is comprised of: a first-in first-out; a write buffer connected between the MBUS in the active mode and the first-in first-out; a write controller for storing data stored at the write buffer at the first-in first-out; a read buffer connected between the MBUS in the standby mode and the first-in first-out; a read controller for simultaneously storing data stored at the first-in first-out, at the read buffer, checking status of the MBUS in the standby mode, and outputting the data stored at the read buffer to the MBUS in the standby mode.
