Abstract
PURPOSE:To improve the processing efficiency by increasing a row address decoder in accordance with a row output circuit provided by one piece or more. CONSTITUTION:Row I/O circuits 4, 8 being row output circuits are provided by one piece or more, and also, in accordance with the row output circuits 4, 8, row address decoders 3, 7 are increased. Accordingly, when one piece of word line in a memory cell array 1 has been selected by an address decoder 2, a data of (b) pieces of memory cells whose word lines are common are inputted to each of the row I/O circuits 4, 8. In such a way, by changing an address signal inputted to the row address decoders 3, 7 corresponding to the row I/O circuits 4, 8, data whose addresses are different are selected simultaneously and outputted, and an equivalent operation to an access to a RAM at a high speed is obtained, and a write operation is also executed in the same way.
