Patent ID: 8174872

Claim:
A nonvolatile latch circuit, comprising: first and second inverters cross-coupled to hold 1-bit data; first and second magnetoresistive elements each having first to third terminals; and a current supply circuitry configured to supply a magnetization reversal current for changing magnetization states of said first and second magnetoresistive elements in response to said 1-bit data, wherein a power terminal of said first inverter is connected to said first terminal of said first magnetoresistive element, wherein a power terminal of said second inverter is connected to said first terminal of said second magnetoresistive element, wherein said current supply circuitry is configured to supply said magnetization reversal current to said second terminals of said first and second magnetoresistive elements, and wherein said third terminal of said first magnetoresistive element is electrically connected to said third terminal of said second magnetoresistive element.
