Abstract
A semiconductor integrated circuit includes: a memory cell array including a plurality of SRAM memory cells; a characteristic measuring circuit including a plurality of transistor circuits connected in parallel; and a first terminal. The plurality of transistor circuits each include a first transistor configured in the same manner as one of transistors included in one of the SRAM memory cells. The first transistor is connected so as to control current between the first terminal and a node at a reference potential according to a voltage supplied to a gate of the first transistor.
