Patent ID: 6876226

Claim:
An integrated digital circuit comprising: a logic circuit portion which takes one of at least two different logic states in accordance with provided control signals; and a non-volatile storage component, which non-volatile storage component takes one of at least two different logic states based on a non-destructive programming, wherein the non-volatile storage component is fabricated from a material such that said non-destructive programming is based upon changes in the magnetic permeability of the non-volatile storage component, which non-volatile storage component keeps a programmed logic state for a basically unlimited time and independently of a power supply until a new programming occurs, and which non-volatile storage component is programmed by and in accordance with each change of the logic state of said logic circuit portion, wherein said non-volatile storage component is connected to said logic circuit portion, and wherein said logic circuit portion comprises a pair of complementary metal oxide semiconductor (CMOS) transistors connected to each other, an output of said logic circuit portion being provided at said connection between said CMOS transistors, and wherein said non-volatile storage component is connected to said output of said logic circuit portion.
