Abstract

A semiconductor device includes: a first latch circuit that includes a first inverting circuit, a second inverting circuit, a third inverting circuit, and a fourth inverting circuit; a first first-type well region; a second first-type well region; and a second-type well region. In a plan view, a distance between a drain of a first-type MOS transistor in the first inverting circuit and a drain of a first-type MOS transistor in the third inverting circuit is longer than a distance between the drain of the first-type MOS transistor in the first inverting circuit and a drain of a first-type MOS transistor in the fourth inverting circuit.
