Abstract

A memory is organized with many memory subspaces (db<i>) each including their own read-out circuit (SA<i>). At least one redundant column (Blred) is provided within each subspace in order to compensate for at least one defective column of said subspace. A memory controller is provided for interacting with the memory via a write bus (TD) and a read bus (Q). The memory controller generates a signal (TD<i>) for enabling the redundant column. This signal is provided so as to be conveyed to the read-out circuits of the memory to which the write bus (TD) is connected. Thus, one enables, via the read-out circuits, the redundant column of the memory subspaces which are associated with a defective column address.
