Abstract
To resolve problems associated with the use of an AUDIO type memory with defective cells without concern for groups of defective cells in such memories, the sounds to be recorded are stored at random addresses, or rather pseudo-random addresses, in the memory. It is shown that, by storing the sounds in this way, it is possible, during the reading operation, by following a same pseudo-random sequence, to restore a coherent sound. At the same time, the device is not demanding in regard to the quality of the memories used.
