Semiconductor integrated circuit

A semiconductor integrated circuit, comprising:

• first to Nth input wires, N being an integer larger than 1;
• a first look-up table (LUT) comprising:
• a first memory group comprising 2N memories;
• a first output terminal;
• and
• a first multiplexer comprising first to N-th stage switch groups, the first stage switch group being connected to the first memory group, the N-th stage switch group being connected to the first output terminal, the i-th stage switch group comprising 2(N-i+1) switches and being controlled by a signal input from the i-th input wire, i being integer ranging from 1 to N;
• and
• a second LUT comprising:
• a second memory group comprising 2N memories;
• a second output terminal;
• and
• a second multiplexer comprising first to N-th stage switch groups, the first stage switch group being connected to the second memory group, the N-th stage switch group being connected to the second output terminal, the i-th stage switch group comprising 2(N-i+1) switches and being controlled by the signal input from the (N-i+1)-th input wire.

A semiconductor integrated circuit, comprising:

• a plurality of input wires;
• a memory group comprising a plurality of non-volatile memories;
• a first power-supply-control switch provided between a power-supply/ground wire and a part of the non-volatile memories and controlled with a signal input from one of the input wires;
• a second power-supply-control switch provided between the power-supply/ground wire and the other part of the non-volatile memories and controlled with the signal input from the one of the input wires;
• and
• a switch group connected to the non-volatile memories and controlled with a signal input from the other of the input wires.
