A semiconductor memory device has a redundant memory cell, wherein faulty memory cells are replaced with redundant memory cells during the production. The memory device comprises a forced release circuit for releasing the replacement with the redundant memory cells, for example, by applying a voltage different from the normal voltage to one terminal of the device. Thus, the faulty state, and the c...

A memory is described which incorporates redundancy in the form of one or more redundant columns. An applied binary address is first distributed between predecoders which form a 1-out-of-2 code from n bits received. For each non-redundant column there is available a part of a main decoder, each part receiving a different combination of the bits supplied by the predecoders, thus selecting the co...
