<p>Provided is a data writing method for reading stored data at first and then performing a writing action. By a write data selecting circuit for switching the data to be written in an SRAM cell, the write data from the outside is written in the SRAM cell selected with a column address, and the stored data of the SRAM cell itself is written back in the SRAM cell unselected with the column address. This constitution makes it possible to arrange the memory cells of the different column addresses adjacent to each other.</p> |
