Abstract

PURPOSE:To ensure a designation for the page mode action and to shorten the access time and the cycle time by having a comparsion between the first address information group of the preceding action cycle and the first address information group of the next cycle. CONSTITUTION:Semiconductor memory unit 2 accepts (7) action request signal 12 from arithmetic unit 1. And signal 12 is connected to address register 3 to be used as the set trigger signal of address information 11. Among information 11 set through register 3, first address information group (low address) 32 is transmitted to address selector circuit 5 and action mode decision circuit 6, and second address information group 31 is sent to address selector circuit 50. At the same time, action designation signal 71 (a) and timing signal 84 (used as the strobe signal to decide whether information 11 has a coinidence between the preceding cycle time and the next cycle time) are connected to circuit 6. Thus, to carry out the action of the page mode or not is decided, and page mode signal 61 is delivered to be transmitted to timing circuit 8.
