  • Semiconductor device
    Patent number: 8952721
    Abstract: Disclosed is a semiconductor device which is intended to reduce the total number of storage element blocks that constitute a desired logic circuit. The semiconductor device includes N address lines (N is an integer equal to two or more), N data lines, and a plurality of storage sections. Each of the storage sections includes an address decoder for decoding an address supplied via the N address lines to output a word select signal to word lines; and a plurality of storage elements which are connected to the word lines and the data lines, each store data that constitute a truth table, and input or output the data via the data lines in accordance with the word select signal supplied via the word lines. The semiconductor device is adapted such that the N address lines for the storage sections are connected to the respective data lines of other N ones of the storage sections, while the N data lines for the storage sections are connected to the respective address lines of other N ones of the storage sections.
