A semiconductor storage device with serial-parallel conversion function which enables operation to be high speed while shortening a period of input/output of data. Data inputted in serial condition is converted in parallel condition to be written into memory array, before reading-out the data in parallel condition from the memory array to be outputted in serial condition. There is provision of a memory array whose speed of input/output of data is high, and a memory array whose speed of input/output is regular. High speed memory array stores therein data which is inputted finally and data which is outputted in the first place.
