ABSTRACT:
In inputting control information for setting access conditions in a system having a common data bus (3), when a predetermined bit string making up an access condition setting command is inputted to predetermined terminals which are not data input/output terminals (S3), the predetermined terminals are set as control information input terminals (S5) and inputted control information is temporarily maintained in a non-volatile memory device (S13). When inputting of control information is completed (S15), the control information that has been temporarily maintained is stored in a non-volatile memory region all at once (S17). During an access condition setting operation, the data input/output terminals are released (S7) and the data bus (3) is made available to other banks or devices (2) so that data transfer efficiency of the system can be improved.
