Abstract

A method of toroid writing and reading of information, consisting in that from toroid-like patterns made from a magnetic material the structures are organized, comprising information and reference patterns, having a closed magnetic flux of the appropriate twisting direction. When writing the alternative information, on changes the twisting direction of the closed magnetic flux in appropriate information patterns by exposing them to the coordinated in the time and magnitude action of mutually intersecting biasing and magnetic reversal alternating magnetic fields, and when reading the information, one acts on the information and the reference patterns by an alternative biasing magnetic field, afterwards detects the output signals and on the character of their responses determines the value of the information unit written into the information pattern. The memory cell comprises a toroid-like element, through the axial opening of which a signal busbar passes, developing a vortex magnetic field in the toroid-like element, and the biasing busbar situated off the toroid-like element develops in the toroid-like element the magnetic field being transverse relative to the vortex magnetic one. The memory device comprises a memory array (13), constructed by the information memory cells with K biasing busbar (15) and L signal busbars (16). The busbars (15) are connected to the biasing current generating unit (20) and the busbars (16)—to the data writing current generating unit (21). The biasing busbar (15) and the signal busbar (18) of the reference memory cell are attached to the biasing current generating unit (20) and to the triggering unit (22), correspondingly. The signal inputs of units (20) and (21) are connected to the signal generator (19), and their address inputs to the address decoder (23). The outputs of the busbars (16) and the busbar (18) are connected to the detectors assembly (24), whose output is connected to the electronic control unit (25). The controller (26) controls the operation of the memory device.
