ABSTRACT OF THE DISCLOSURE A memory cartridge comprises a case, and a printed circuit board housed in the case is connected to a data processing unit including a microprocessor when the memory cartridge is loaded therein. A memory cooperating with the data processing unit is installed on the printed circuit board, and a memory area of the memory is divided into a plurality of banks. A multi-memory controller installed on the printed circuit board includes a plurality of registers into which data representing bank change-over conditions given from the microprocessor are loaded. An address for changing-over the memory bank is outputted in response to the content of at least one of a plurality of registers. Thus, by changing the above-described data, the microprocessor can specify an arbitrary bank at an arbitrary timing and utilize that bank.
