Abstract

PURPOSE:To arbitrarily set a page size by corresponding to the bit length data of page address data set to a register, controlling respective special high order and low order bus switching parts and outputting the page and respective address data in the page. CONSTITUTION:Bit length data 50 of page address data 60 are set to a page size register 7, the bit width of a page register 4 corresponds to the maximum value of the data 50, and the connection of the respective bits and respective corresponding high order bits of a second address bus is respectively switched at a bit unit by a high order bus switching part 5. Further, the connection of the flow order bit of the second address bus corresponding to the space width of a page classified by the minimum value of the data 50 and the corresponding bit of a first address bus is switched to a bit unit by a low order switching part 9, switching parts 5 and 9 are controlled by a bus control part 8, and the data 60 and address data 61 in the page are outputted to the second address bus.
