Description

The drawing shows a schematic diagram of the zapom: inayush, its devices, made according to this invention.

The storage device contains ilastinum / from a magnetically uniaxial material with cylindrical magnetic domains 2, and placed in a magnetic field 3 of the source of the magnetic bias zero. On ilastin / there are bucket ferromagnetic aiylikaini 4 with loops 5 at the ends, current vertical control conductors 6 connected to the decoder 7, horizontal control conductors 8 connected to the decoder 9. The plate / covered with a screen 10 with holes coaxial holes looped 5 bucket-shaped applications 4. In front of screen 10 there is a source // of polarized light. On the other hand, the plates / are located the analyzer 12, the photoattachment 13, realized in the form of two independent photosensitive elemeitosis, the outputs of which are included in the differential circuit 14.

The operation of the storage device proceeds as follows.

The zero state of the cell is characterized by the presence of a cylindrical domain 2 formed by the source of the displacement field 3 under the free end of the applications 4, a single one by the presence of domain 2 at its average angle, and the indication one by the loop 5. The recording of the unit information in the selected cell is carried out using a sequence of current pulses arriving at conductors S and 5 from decoders 9 and 7. In other words, the polarity of the pulses is such that domain 2 moves under the selected configuration 4 from its free end to the middle angle. After that, in the half-selected cells, the initial state is established by applying to the conductor 8 a pulse of opposite polarity. The indication of a single cell is carried out by translating house 2 under loop 5 of application 4 with the corresponding series of pulses. At the same time, if a unit was recorded in the cell, house 2 goes under loop 5, if zero, house 2 remains in a bullet state.

After the installation of house 2 iodine 5, the source of the field of living light // emits a pulse of luminous flux, but the analyzer / 2 is configured so that it transmits only part of the luminous flux that interacted with domain 2, which is sweat loop 5.

When exposed to part of the luminous flux passed through the analyzer 12, one of the halves of the photodetector 13, the latter generates a signal that acts on the differential circuit 14.

The separation of the photodetector 13 into two independent parts, each of which is optically connected with half the plastic /, and its inclusion in the differential circuit 14 ensures mutual interference of the interference signals that occur when indicating the bullet state and cells. In this case, domain 2 is missing in any loop

ai) 4.

After the indication of the single state of the selected cell domain 2, the average angle of the application 4 is transferred again. Thus, in the proposed storage device, a selective reading of information was carried out.

The transfer of the cell from the single to the zero state is performed by iodine of the corresponding pulse train, which moves the domain 2 to the free end of the application 4.

The proposed device allows 1t to simplify the design and improve the efficiency of the matrix memory and domain structures.
