PROBLEM TO BE SOLVED: To provide a comparator with non-complementary input structure in order to improve technical problems such as power consumption, number of transistors and a throughput delay in a conventional comparator circuit with a complementary input structure. SOLUTION: The non-complementary comparator includes an evaluation element such as a memory cell, a differential amplifier, or another type of circuit capable adapted to perform an evaluation function, and at least first and second input legs each coupled to a corresponding one of a first and second node of the evaluation element. However, after the evaluation, the output attains a full digital value but suffers no defective power consumption. Transistors form a cross coupling random access memory cell and perform a comparison of contents of the two legs during the evaluation.
