Abstract

A data controlling unit activates a predetermined number of data terminals according to a mode signal and changes a bus width of external data signal. According to the mode signal, an address controlling unit selects a predetermined number of bits of an internal address signal outputted from a controller and outputs the selected bits as an external address signal. Specifically, the address controlling unit selects upper bits of the internal address signal when the bus width of the external data signal is increased according to the mode signal. Therefore, it is possible to prevent occurrence of an unused external address terminal, enabling the increase in accessible external memory capacity.
