Abstract: The device includes a decoding logic mean (40) having chip select pairs (CS1, bar CS1 - CSn, bar CSn) connected to outer input taps selectively to select the single chip corresponding to the logical combination of the extended address. The decoding logic means comprises a number of inner logic means (30-1 - 30-N) which number is same to the selected chips, and an AND gate multiplying the outputs of the inner logic means logicaly.
