PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit which converts a very small logic level of about 0.5 V into a 1 to 3 V of conventional logical level, and is low power consumption with a large allowance with respect to device characteristics, and further has a level conversion circuit that prevents deterioration of operational speed. SOLUTION: A semiconductor integrated circuit, of which each output of low voltage operation logic circuit and its logically converted output, is connected and driven to two outputs of a cross latch, which is composed of cross connection of two FETs via each gate grounded FET. Further two of the cross latch are set and a third cross latch (301, 302) is connected between the first and second output which are level converted by these two cross latches (the first and second cross latches).
