Title: Apparatus and method for restoring cell storage regions in an ATM switch and method therefor

Abstract: An apparatus for restoring the cell data storage regions of the common memory in an asynchronous transfer mode (ATM) switch system, comprises a first multiplexer for multiplexing the cell data with the header and content data separated, a second multiplexer for multiplexing the addresses generated from a plurality of FIFO registers, an address checker for checking the addresses from the second multiplexer to generate a first and second address signals if the addresses are checked normal, an address memory storing all addresses of the common memory in error state to selectively convert the addresses into normal state according to the second address signal from the address checker, a controller for checking the address memory at predetermined intervals to restore an address stored in error state to a normal state, and an address multiplexer for generating an idle address to an IAP according to the first address signal and address restored signal.
