Description

one

The proposed device relates to the field of computer technology and: can be used in secure devices in which information carriers are cylindrical magnetic domains (CMD).

Known annihilator dividers are made on the Chevron ferromagnetic appliqués that form. two channels of advancement of domains moving the CMD in two three-dimensional directions, and containing a control rod located above the channels 1 of the CMD-1 movement.

However, the known devices have the following disadvantages: the operation of the dividers-annihilators is carried out by bipolar pulses; the devices do not allow selective erasure of information in the promotion channels of the CMD.

Of the known devices, the closest to the technical essence is the divider of the cylindrical magnetic domains, containing a magnetically uniaxial film with cylindrical magnetic domains with control structures located on it.

in highly-directional canapes of advancing nilindric magnetic domains on chevron ferromagnetic applications, with the ShchSha control connected to the source of the control magnetic field and forming over two chevron ferromagnetic applications of different promotion channels of the chromosome nos.

The device has the following disadvantages: it does not provide independent circulation of information in the promotion channels of the domains without excitation of the control bus; does not allow for the selective erasure of information in the promotion channels of the CMD.

The present invention overcomes these disadvantages.

The aim of the invention is to expand the functional possibilities of the device by independently circulating information without exciting the control for each 1 st control magnetic field. This is achieved in that the device comprises additional channels advance cylindrical magnetic domains formed on the ferromagnetic cruciate applications, two process which propshopolozhnyh soedsh- enes with vertices shevronovvah ferromagnignyh Appley ka s, and the other two form the ridge with the free ends of chevron-tions ferromagnitpyh apgshika passive dilators cylindrical magnetic domains, the tops of the chevroNew ferromagnetic applications are displaced in opposite directions relative to each other, and It forms annihilation loops over the sections of the propagation channels of cylindrical magnetic domains, corresponding to two opposite directions of the magnetization vector of the control magnetic field, which coincides with the directions of the free processes of the cruciform application. The divider-annihilator of cylindrical magnetic domains presented in Fig. 1 is made as follows: two input 2 and 3 and two output 4 and 5 counter-directional CMD promotion channels located symmetrically relative to their additional promotion channel of CMD are located on the surface of a magnetically unresolved film 1 with CMD, made on a cruciform ferromagnetic application 6 and the etching bus 7, the source of the control magnet 11C -o-floor (not shown in the drawing). The device works as follows. FIG. 2 illustrates erasing the information and recording the place of the new information. If the impulse currents are not passed through the control, each of domains 8 or 9 moves along the corresponding transmission path of the CMD (Fig. 2, a-b). When a pulsed current i is passed through the control bus at the moment of time when the magnetization vector is directed upwards (FIG. 2, b-c), domain 8 can be wired by the vortex magnetic field of a conductor with a current that times the corresponding bit of information . Domain 9, moving along one short circuit of channels prg. : Yeni G1MD (Fig. 2, c) plant No.: It is established on the adjacent processes of the cruciform ferromagic ashtlication (Fig. 2, g). When an I-Y pulsed current is passed through the control bus, the latter is divided into two CMDs. Thus, the proposed device allows all the necessary write operations for the accumulator, readout and selective CTHpaHiiH information to be performed via one divider-annihilator control bus. The asymmetric configuration of the device's ferromagnetic application allows organizing independent circulation of information in the storage registers and register st zi without excitation (for each period of the control floor) of the control current scale. The preparatory divider-anshilor has the following advantages: it does not require the use of a special bus in the drive to erase information in the storage registers, which substantially simplifies the structure of the drive and expands the functionality of the device; copies of the information sequence / anost of the CMD, remaining with in the write register, can be destroyed by the control bus of the divider-annihilator, which allows to significantly reduce the time to access the drive; the possibility of organizing independent storage of information in the storage registers and communication registers in the storage device without exciting the control current bus simplifies device control and increases its reliability and the storage device as a whole.
