Abstract
A semiconductor integrated circuit device formed with a single semiconductor substrate has, in one embodiment, an input buffer for receiving an input signal, memory blocks each producing an output signal responsive to the input signal and an output data selecting circuit for selectively transferring an output of one or more of the memory blocks. The input buffer, memory blocks and output data selecting circuit are arranged on the single semiconductor substrate in an order of progress of signal processing operations to be performed in the semiconductor integrated circuit device.
