Abstract

PURPOSE: To simplify the constitution of a memory driving circuit by carrying out the page change of memory by placing a final data of the respective pagaes as a judgement standard.
CONSTITUTION: The page specifying judgement circuit 7 counts a specific instruction by a program counter 6 every time when the specific instruction is produced from a designated page of the memory 4 and judges the final data of that page. Then, together with the judgement of the final data, the contents of the page designating latch circuit 5 are changed and the page change is carried out without using a complicate circuit, etc. Accordingly, the constitution of the memory driving circuit constituting the page construction becomes simple.
