Description

The invention relates to computing and can be used in the construction of integrated operational and logical memory devices on cylindrical magnetic domains (CMD).

The purpose of the invention is to expand the field of application of the magnetic threshold element by implementing threshold functions with negative and zero thresholds.

The drawing shows a schematic diagram of a magnetic threshold element. A magnetic threshold element contains a magnetically uniaxial film 1 with CMD on the surface of which the shift register 3 of the CMD is located, connected to the CMD generator 4, the 5 SchS annihilator and through channels 6 of the preferred promotion of the CMD with dynamic CMD traps the second 7 and the third 8 Additional groups, the main information channel 9 of the advancement of the TsShch, connected via switches 10 TSUB of the first group with dynamic traps CMD of the second additional group 7, with an igil 5 CMD and through channels of forced M and preferred 12 advance CMD with older dynamic traps SchSch of main groups 13 and with dynamic trap 14 CMD connected via switches 15 CMD with output channel 16 of advance CMD, additional information channel 17 of advance SchSch connected through CMD switches 18 of the second group with dynamic traps 8 CMD of the third additional group, with the annihilator 5 CMD and through channels 19 of the preferred advancement of SchSch with dynamic traps of CMD first tion group magnitosv of which are connected with the main information channel 9 and CMD advance with corresponding channels 11 of advance forced CMD, the dynamic trap main groups and the first 13 d Modes magnitosv group 20 are connected to the bus 21, the erase CMD.

The magnetic threshold element works as follows.

In the initial state, the dynamic traps of the SchSchCCH of additional groups 7 and 8 are filled with domains 2 and 2 of the CMD sequence, which is continuously moving along the shift register 3

CMD from generator 4 CMD to annihilor 5 CMD. When CMDs are output from dynamic CMD traps of additional groups, they are filled with domains from the CMD shift register 3 through channels 6 of the preferred advancement of the CMD.

The arrival of input logic variables, represented by current pulses, into the conductor buses of switches 10 and 18 of the CMD, which are inputs of a magnetic threshold element, leads to the output of domains from the corresponding dynamic CMD traps of the second 7 and third 8 additional groups to the main 9 and additional 17 information channels promotion of CMD. Domains received in the additional information channel 17 of the advancement of the CMD fill the dynamic traps of the CMD of the first additional group 20 in accordance with the following rule: if the dynamic trap of the CMD is domain-free, then the CMD from the additional information channel 17 of the promotion of the CMD on channel 19 the preferred advancement of the CMD enters this dynamic CMD trap, otherwise the domain does not leave the additional information channel 17 of the CMD advancement due to the presence of magnetostatic forces vi house between them €; nom comprised within the given dynamic bubble trap, and by further advancing Referring traffic channel TSSCH advance, supplied to the next in the order of the dynamic bubble trap 20, the first additional groups.

If the number of domains received in the additional information channel for the expansion of the CMD exceeds the number of dynamic traps of the CMD in the first additional group, then the domains that remain after filling in the dynamic 1-GUSH domain are output to the annihilator 5 of the CMD and are destroyed.

The first time the dynamic traps of the CMD of the first additional group of dynamic traps of the CMD are filled last.

Then, the CMDs moving along the main information channel 9 of the advancement of the CMD arrive at the dynamic CMM traps of the central motion control of the main groups 13 and fill this main group of dynamic traps of the CMD along channel 11 of the forced advancement of the CMD, if in the senior dynamic trap

An additional group of 20, magnetically connected with this channel of forced advancement of the 1st CSC, contains a domain and the highest dynamic trap of this main group is free. Otherwise, the domain goes to the next in order main group of dynamic CMD traps or to the dynamic trap of 14 data centers. The dynamic trap 14 is filled with a domain on the preferred channel of the SchCHS, if it is free, otherwise the domain is advanced along the main information channel of the advance of the CMD further to the annihilator 5 of the CMD and is destroyed. A domain that enters the dynamic trap of the main group's CMD is moved to the next neighboring dynamic trap of the main group of the main dynamic groups if one of the subsequent dynamic traps of the ESC is missing the domain, or remains in this dynamic trap - otherwise. If this basic group of dynamic CMD traps is completely populated with domains, then the domain located in its upper dynamic trap interacts with domains that are promoted along the main information channel of advancement of the ESCAP, and compensates for the interaction on them of the domain located in the corresponding upper dynamic domain.

As a result, the domains remain in the main information channel of the promotion of the CMD and advance along it further. 5 After filling in the dynamic trap of the SchSCH, which interconnects with the main information channel of the advancement of the SchS, the dynamic trap 14 of the SCHOD is polled, the state of which determines the value of the implemented threshold function. To do this, the CMD switch 15 is energized and the contents of the dIf of the clean trap 14 are output to the output channel of the SCHSH promotion. In this case, a single value of a given threshold function is realized if the polled dynamic trap contained a domain, otherwise a zero is realized.
