Abstract

The invention relates to computing and can be used in information storage devices. The aim of the invention is to reduce information reading time and increase device reliability. This is achieved due to the fact that in the drive containing the storage registers, the I / O register, the generator and the sensor, the storage registers are connected to the I / O register via the replicators - the switches, and the input of the new information from the generator and the return of the information block to the half-selected drives The x is implemented using switches that connect the generator to the I / O register and the end of the I / O register to its beginning. As a result, the probability of loss of information is reduced and the recovery time of the stored data is reduced. 2 Il. I (l oe o 4 o

Description

The invention relates to computing and can be used in information storage devices.

Tse. 1 of the invention is a reduction in information reading time and an increase in reliability of the tip.

FIG. 1 shows a block diagram of a storage element for a matrix storage device on cylindrical magnetic domains; FIG. 2 is a diagram of its inclusion in a matrix memory device.

The accumulator is a magneto-uniaxial film 1, on which permalloyed applications and electrical conductors are located, defining the structure of the accumulator. The storage unit consists of registers 2; ... 2.1 storage, which are connected to input / output register 4 by means of switch replicators 3 | ... 3n. The storage element contains a generator 5, the output of which is connected to the input-output register 4 by means of the first switch 6, and a sensor 7, the input of which is connected to the end of the input-output register 4. In addition, the beginning of the I / O register is connected to its end by the second switch 8. The replicators switches Sj ... 3 "have a common electric bus 9 of control, switches 6 and 8 have a common electric bus 10 of control, the matrix element of drive 11, , /; (t - columns K. column), control bus 12, sensor output 13. The storage element is included in the matrix memory in such a way that the control engines 9 of the switch replicators 3 of all the 1 I storage elements located in one row of the matrix, connected in series. In addition, all elements of the accumulator 11 located in the same column of the matrix are connected in series with the control 10 of the switches 6 and 8 and the bus 12 of the generator 5, and the outputs 13 of the sensors 7 are connected in series.

The drive works as follows.

In the read mode, the required information data block is searched in the selectable element of the matrix accumulator (for example, 112.2) by advancing information simultaneously on the registers 2, ... 2p of storing all the elements of the accumulator

111 1 ... 11 „, i matrices. By applying replication current to Tin 9 of the selected row of the matrix (when sampling from accumulator 112.2 - second row) in the accumulator elements of this row by means of switch replicators 3i ... 3n information blocks are transferred (copied) from registers 2 | ... 2 These are stored in I / O registers 4, after which they are pushed through the I / O registers 4 to the sensors of the accumulator elements of the selected row. By applying reference voltage to the electrical outputs of the 13 sensors 7 of the selected column (when sampling

accumulator element 1 b, second column), the required information block is sequentially read from the selected accumulator element (for example, 112.2).

Thus, reading is performed only from the storage element located at the intersection of the selected row and the selected column. In all half-selected elements of the accumulator of the selected line

 sensors 7 are not supplied with reference voltage. The passage of the CMD under them does not lead to the appearance of a readable signal. In all the semi-selected elements of the accumulator of the selected column, the information in the input-output registers 4 is missing and, therefore, does not flow to the sensors 7. Thus, information is not read in all the semi-selected and, obviously, unselected elements of the matrix accumulator.

0 In the recording mode, the required information data block is searched in the selectable element of the matrix accumulator (for example, 112.2) by advancing information simultaneously on the storage registers 2i ... 2n of all the elements of the accumulator

 111 1 ... I m k matrices.

By applying the switching current to the line 9 of the selected row (when sampling from the accumulator 1122 - the second row) in the accumulator elements of this row the information

The blocks are transferred (switched) from the registers 2i ... 2, storage to the 4 I / O registers.

Giving control signals to the electrical inputs 12 of the generators 5 of the selected column (when the element of the accumulator element 5 5 112.2 is sampled - the second column), the recorded information block is sequentially entered. Then, by supplying current control signals of their signals to bus 10, switch 6 converts the input information block into input-output register 4.

 A bus of 10 unselected matrix columns is fed to a sequence of current control signals that return the output information block from the end of the I / O register to its beginning through switch 8. The time of the start of data input through the generator 5 to the selected drive element and the beginning of the supply of sequences of currents to control switches 6 and 8 are selected so that the information blocks in the storage elements in the selected and unselected columns go to switch replicators 3 of the selected row one TERM. In doing so, the current signals supplied to the bus 10 to control the switches 6 and 8 should differ

5 in phase or polarity. As a result, in the input-output register 4 of the selected storage element, the input information block will be located opposite the storage registers. In the I / O registers 4 of all half-selected elements of the accumulator of the selected row, the information block previously derived from the storage registers will be found. By supplying the switching current to the bus 9 of the selected line, the information block in each element of the accumulator 11 is transferred by means of the replicator switches 3. To the registers 2 ... 2-n storage.

Thus, in the selected storage element, in place of the information block, derived from the storage registers, the entered information block will be recorded. In the half-selected elements of the accumulator of the selected line, the information block derived from the storage registers returns to its place. In the remaining elements, the drive is not written (switching the information block to the storage registers). In this case, the semi-selected elements of the accumulator of the selected column entered into the I / O registers are then output without reading information by advancing through the I / O registers to the sensor 7.
