ところは大きい。As is clear from the above description, the present invention has a configuration in which address information is obtained using four multi-value logic signals, so the number of address information lines that appear when accessing a 3-memory device is lower than that of the conventional 241 logic signal. The number of bins in the multi-chip array can be reduced by 1/2 compared to the one that used the integrated circuit, and the number of bins in the memory array can be reduced by 64 bits or more when it is integrated. 1iI!
