Abstract
PURPOSE:To reduce the increase of a chip area according to the addition of an error detecting and correcting function by sharing the selection of most memory cells at the time of reading, writing, and at the time of detecting and correcting the error by one decoder. CONSTITUTION:A partial selection of the selection of the memory cell 1 of an information bit at the time of reading and writing is executed by the use of a second decoder 17 and a partial selection of the selection of the memory cell 1 of the information at the time of detecting and correcting the error is executed by the use of a third decoder 19. Then, a first decoder 14 is shared for selecting most memory cells 1 at the time of reading, writing and at the time of detecting and correcting the error. Thereby, the increase in the chip area due to the addition of the single error detecting and correcting function can be reduced.
