Abstract
A data input/output managing device, particularly for non-volatile memories that comprise at least one matrix of memory cells. The managing device comprises: at least one bidirectional internal bus for the transfer of data from and to the memory; a redundancy management line that is associated with the internal bus; means for enabling/disabling the transmission, over the internal bus, of the data from the memory toward the outside; means for enabling/disabling access to the internal bus on the part of data whose source is other than the memory matrix, for transmission to the memory matrix; and means for enabling/disabling the connection between the outside of the memory and the redundancy line during the reading of the memory matrix and during its programming.
