METHOD FOR USING SEMICONDUCTOR INTEGRATED CIRCUIT AND SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To store information in an SRAM block in a nonvolatile way, as regards a method for using a semiconductor integrated circuit provided with the SRAM block and the semiconductor integrated circuit.

SOLUTION: The conductance of one pulldown transistor is varied by making drain current flow to the one pulldown transistor between a pair of pulldown transistors constituting at least one SRAM for nonvolatile information storage among a plurality of SRAM cells.
