ABSTRACT:
A memory cartridge having a case and a printed circuit board housed in the case is connected, in use, to a data processing unit including a microprocessor and a picture processing unit. A memory cooperating with the data processing unit is installed on the printed circuit board, and an 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 microprocessor generated data, representing bank switching conditions, are loaded. An address for switching the memory banks is output 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 a specific bank at a specific time and utilize that bank.
