Abstract

PURPOSE:To enable an arbitrary logical operation through electric rewriting at any time, suitable for large-scale circuit integration with good storage efficiency, by locating tri-stable storage cell in matrix and making logical operation according to the content of storage of storage cell with binary logical input signals. CONSTITUTION:A write-in controlling signal inputted from the outside through a signal line 103 is inputted to an AND logical array 2 in M rows and N columns via either one of signal lines 104-1-104-N with a write-in control circuit 1.M sets of binary logic input signals are inputted to an AND logical array 2 from the outside through signal lines 201-1-201-M, and M sets of ternary write-in input signals are inputted to the signal lines 202-1-202-M, and N sets of logical output signals in AND operation are inputted to an OR logical array 3 in L row and N column locating tri-stable storage cells in matrix via signal lines 203-1-203-N. Further, L sets of logical output signals in OR operation are outputted to signal lines 301-1-301-L from the OR logical array 3.
