Abstract
A device for generating memory addresses is provided that is suitable for generating memory addresses transposed in row/column directions with reference to a data successively stored therein along with a mobile station by using the same, and a method for writing/reading a data. The device includes a counter that generates 2.sup.2n successive addresses in 2n bitstreams to provide row direction addresses, and a barrel shifter that shifts the generated 2n bitstreams by `n` bits to provide column direction addresses. Thus, circuitry of a picture encoder of the mobile station or of an interleaver in a mobile communication system is reduced, and a faster operation speed is obtained.
