Abstract: The device has a memory cell operated in a mode, in which the cell is directly operated as a memory device for error-correcting code (ECC)-information. The cell is operated in another mode, in which the cell serves as the memory device for storing information, which is different from the ECC -information. A signal control device (CTRL) is used for signaling in such a manner that the cell is operated in the former or latter mode. An independent claim is also included for a method for operating a semiconductor memory device.
