A drum memory controller for controlling random access write and sequential read operations of a drum memory in a communications system. Such drum memory controller ( ) may comprise a drum memory ( ) having a predetermined number of rows and rings forming a plurality of memory locations arranged in a sequential time order; a random access write address generator ( ) which generates write addresses using a respective time tag of incoming data for writing data into memory locations of the drum memory ( ) in a random access time order; and a sequential reader ( ) which generates read addresses at a constant rate for reading out data stored in the memory locations of the drum memory ( ) across each row and then sequencing up in rows in a sequential time order.
