Abstract
A layout structure of a small-area one time programmable (OTP) memory using a complementary FET (CFET) is provided. The OTP memory has transistors TP as a program element and transistors TS as a switch element. The transistors TP are three-dimensional transistors of which channel portions overlap each other as viewed in plan. The transistors TS are three-dimensional transistors of which channel portions overlap each other as viewed in plan. The OTP memory of two bits is implemented in a small area.
