SU590829A1 - Decoder with cylindrical magnetic domains - Google Patents

Description

one

The invention relates to the field of computer technology and can be used in memory devices for preliminary logical processing of information to be stored.

A decoder is known on cylindrical magnetic domains (CMD), containing a magnetically uniaxial film with CMD, on which are located generators of domains median with dual promotion channels of CMD formed by T- and J-shaped ferromagnetic applications, and control lines that form above the right end parts mi T-shaped elements of the corresponding channels and the movement.

The closest technical solution to the invention is a decoder on cylindrical magnetic domains containing a magnetically single axis CMD plate, on the surface of which there are channels for advancing domains from ferromagnetic applications, whose inputs are connected to the output of the domain generators, control buses, control sources and zero offset 2. Such devices have a large number of control buses () and a sufficient speed.

The purpose of the invention is to increase the speed of the decoder and reduce the number of tires. The goal is achieved by the fact that each control bus is located through 2 () channels of native domains over ferromagnetic applications corresponding to the direction of the control zero vector O and 90 °, and through 22 ("- 1. II channels of domain advancement over

ferromagitic patches corresponding to the direction of the control field vector 180 and 270, where n is the order number of the control bus, a, groin.

In addition, the sciaceae over the areas of ferromagitia applications are made in the form of metal.

The drawing shows the scheme of the proposed decoder for the four-bit address word ().

The magnetically single-axis plate 1 with CMD contains 2 domain generators, domain promotion channels 3-18, formed by a ferromagnetic application system, and control buses 19 (bus No. 1) and 20 (bus

Ao 2), which cover the corresponding CMD-position of the channels and mobile domains (O, 90, 180 and 270 °). Domains are passed to the output of the decoder only through one of the channels 3-18, which is determined by the succession of a series of current pulses sent to

each of the control buses. The table explains the operation of the decoder (1 and O, respectively, the presence and absence of the pulsed annihilation of the CMD in the control buses).

Each of the right tires can be shifted relative to the CMD positions by 0.257 (90 °), 0.5G (180 °) and 0.757 (270 °), where G is the period of the filling field.
