Description

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

The aim of the invention is to simplify the accumulator

The drawing shows a block diagram of the preserved accumulator.

The drive contains a magnetically uniaxial film 1 with a TsShch 2, on the surface of which channels 3 are formed from current applications, forming closed information storage registers A, switches 5 CMD, element BAN-6, locations in the register

7 records-read CMD, with inputs

8 and 9 and outputs 10 - 12, generators

13 and 14 CMD, interface 15 of two channels, sensors 16 and 17 of CMD reading, element AND-OR 18, located in register 7, with inputs 19

and 20 and outputs 21 and 22, while the outputs 21 and 22 of the element AND-OR are connected to the inputs 8 and 9 of the element BAN AND 6 "

The operation of the accumulator is based on the well-known method of controlling the proliferation of CMD with the help of current applications and current pulse sequences in the plane of the magnetically uniaxial axis. Current pulses, passage through conductive layers, form in them magnetic poles, which interact with the CMP and provide the motion of the latter ..

The drive. Works as follows

In the input mode of the CMD to the storage registers from the generator 13 through the element 15 to the register 7, consisting of current applications, the information sequence of the CMD is received. After turning on the switches 5, this sequence is recorded in registers 4 formed by channels 3 in which information can be moved or stored. . In the read mode, the CMD of register 4 includes switches 5 and information is transferred to register 7, then the generator turns on

14dl write SchSch on input 20 element 18 On the other, input 19 element

18 enters the readable information sequence CMD, From outputs 21 to 2.2 of element 18 in this

In this case, the same information sequences were received that arrived at 19 and 20. Therefore, a single CMD sequence arrives at input 9 of element 6, and information 6 of CMD information enters input 8 of element 6, information from registers 4 is read paraphasically from sensors 11 and 12 from outputs 11 and 12, and 17 and remains at the output 10 connected to the register 7o. Moving on the register 7, the information passes the channel conjugation element 15, gets to the inputs of the switches 5 and switches back to the registers 4 o

In the erase mode, the CMD registers 4 after their switching to the register 7 of the CMD are fed to the input 19 of the element 18. At this time, the generator 14 is turned off. and the inputs of element 18 receive only the information of registers 4. This information falls on the outputs 22 of element 18, Toe. Out of register 5, 7 passes element 6, enters output 11 and passes through sensor 17,
