A nonvolatile memory circuit-a novel approach

A nonvolatile memory circuit using conventionally available components (transistors and magnetic switching cores) operates on the principle of the two distinct impedance levels of a switching core in the irreversible and reversible regions. It has the property of nondestructive read-out and requires no sensing amplifiers. It is believed that the circuit is useful for systems that require low memory capacity, such as from a few bits to a hundred of bits of information.
