Abstract
A memory device has a ferroelectric memory cell block, which is connected via an input/output latch buffer to a data input terminal. The memory device also has a writing period forming circuit that forms a predetermined number of writing periods when writing of data is requested. During the thus formed plurality of writing periods, a control circuit controls the input/output latch buffer to write data to the memory cell block. Thus, a single request for writing of data causes writing of data to be repeated a plurality of times automatically.
