A cell re-sequencer for re-sequencing the cells switched by an ATM switching system, comprises a maximum delay register for setting the maximum delay value by initialization to output the maximum delay value according to internal clock pulses, a base address increment register for increasing the initial value of the initialization set as a base address one by one according to cell time clock pulses, a delay detector for detecting the real delay of a cell from its header, a cell storing address generator for adding the base address to the delay difference between the maximum delay and real delay to generate a cell storing address, a multiplexer for multiplexing the base address and cell storing address according to the cell time clock pulses, and a memory address register for temporarily storing the output of the multiplexer.
