Verifying integrity of decoding circuits of memory matrix by performing at least N or M writing of second words in storage in such way that every line and every column has at least registered second word

摘要

After having written all words to a memory with a same first word (h00), it performs at least N or M writing of second words (h01 hFE) in the storage in such a way that every line and every column has at least registered second word. The second words are different from the first words. Then all words of the storage matrix are read.
