Abstract
In a non-volatile semiconductor memory device capable of programming SRAM data in an SRAM into a non-volatile memory unit while implementing a high-speed operation in the SRAM, a voltage required to program the SRAM data into the non-volatile memory unit can be lowered. Thus, the SRAM can be operated at high speed with a low power supply voltage because the thickness of a gate insulating film of each of a first access transistor, a second access transistor, a first load transistor, a second load transistor, a first drive transistor, and a second drive transistor constituting the SRAM connected to the non-volatile memory unit can be set to 4 [nm] or less. Therefore, the SRAM data in the SRAM can be programmed into the non-volatile memory unit while a high-speed operation in the SRAM can be implemented.
