Abstract

PURPOSE:To increase the reading speed in the page mode, by reading asynchronously the data signals on a common data bus line by means of the residul bits of a row address. CONSTITUTION:In the reading mode, the -RAS is changed to an active state from an inactive state. A line address is fetched to a buffer circuit 5, and the address bits within a part 5a are supplied to a word line driving circuit 2 via a line decoder 3. At the same time, the address bits within a part 5b are supplied to the circuit 2 via a word line driving clock generating circuit 4. Thus a line wire in a memory cell array 1 is driven, and the holding information of each cell is transferred onto the bit wire. Then the state of the -CAS is inverted, and the output of a row decoder 7 selects a sense amplifier 6. Then the data is delivered onto a bus 8. Meanwhile the bit signal and its complement signal supplied from the part 5b are supplied to a bus selecting circuit 9, and the bit signal on the bus 8 is applied to an output buffer 10.
