Abstract
The memory device has a selection device which, when required, ensures that backup memory cells or backup memory cell areas are used instead of memory cells or memory cell areas which cannot be written to or read from properly. Information about the location of the memory cells which are possibly not to be used is actually supplied to the selection device at an instant at which it is not yet definite whether memory cells need to be replaced.
