Description

(54) DRIVE

I

The invention relates to computer technology, in particular, to remembering devices on ferrite cores.

A ferrite core drive is known that contains two matrices, the feieit cores of which are 90 relative to each other, the first winding system stitching the successively pressed lines of the ferrite cores of both matrices, the second winding system stitching the ferrite cores and a third flashing the ferrite cores in axial direction flj.

The disadvantage of such a drive is the presence in the windings of the readout of interference from partially excited cores.

The closest technical solution to the invention is a sprite ferrite core storage device containing two matrices located one above the other, with the ferrite cores of the first matrix being deployed 9O® by

relation to ferrite cores W (matrix matrix, windings, each of which is passed through the ferrite cores of the same row of both matrices, coordinate windings X, each of which is passed through the ferrite cores of the corresponding column each matrix, and the coordinate windings Y, each passed through ferrite cores in axial

10 directions within each group of coordinate windings X, with each of the coordinate windings U passing through the first and last ferrite of the previous line of the first matrix, connected to the gunfire, passing through the next line of the second mat {shy 2j.

Odaako in such a drive is the ratio of the number of lines and columns in

20 cahs is 2: 1, i.e., the matrices are not square and an increase in the number of rows to increase the number of bits results in a strong elongated shape. &

a square matrix for half of the possible addresses will be missing ferrite cores, which leads to a decrease in the speed of such a drive.

The circuit of the invention is to increase the speed of accumulation.

In order to achieve the delivered chain in a known accumulator, each coordinate winding Y passing through the last ferrite core, located on the border between the coordinate coordinate groups X of the previous line of the first matrix, is connected to the coordinate winding U passing through the last ferrite core, frontier

between the groups of coordinate windings X follow the row of the second matrix.

The drawing shows a two-phase drive containing two matrices.

The drive contains the first matrix 1 on ferrite cores 2, the second matrix 3 on ferrite cores 4, the coordinate windings Y 5, the coordinate windings X 6 of the first matrix 1, the coordinate windings X 7 of the second matrix 3, the windings B read. The read windings 8 are passed through the same rows of ferrite cores 2 and 4, respectively, of the first 1 and second 3 matrices. The number 30 of the windings 8 readings per bit is determined by the number of ferrite cores in the column. For this example, the number of read windings per bit is four. The first four windings of the 35 8 crossbar are the first discharge of the accumulator, the next four windings 8 of the readings of the state 1 enter the second discharge of the accumulator. Coordinate windings X 6 and 7 are divided into four groups. Coordinate – dinate windings Y 5 are obtained from a joint, for example, coordinate windings Y s, 5, 5, 5, laid in the axial direction. In this case, each coordinate winding, for example Y 5, passing 45 through the last ferrite core 2 of the second row of the first matrix 1 is connected to the coordinate winding Y 5 passing through the last ferritic core 4 of the third row of the second matrix 3. Coordinate winding Y 3 passing through the boundary core 4, located in the fourth row of the second matrix 3 between the coordinate windings X 6 and 7, is connected to the coordinate winding Y 5, 55 passing through the boundary core 2 located in the fifth line of the first matrix 1.

In the scheme shown in the drawing, the coordinate winding X 6, Y 5, windings 8 readings of the first and second bits, which are shown by thick lines, and ferrite cores 2 of the first and second bits of the first matrix 1, which are shaded in the drawing, are selected.

A soft grinder works as follows.

When writing and {) formatting, for example, a ferrite core 2, which is shaded in the first line of the first 1, pulses are sent to the coordinate axis winding X 6 and winding 8 to count the hank passing through the first row of the first matrix 1, the total amplitude of KOTOfbix is sufficient to switch the shaded ferrite core 2, located in the second row of the j-matrix I, from one stable state to another, corresponding to state 1. During the recording of irformatics, for example, into a ferritic core 2, located in the fifth row of the matrix 1, a current pulse through the winding 8 of the second discharge section does not arrive, and the ferrite core 2 remains in the zero state.

When reading information from ferrite cores 2, KOTOffcie in the drawing, pulses of opposite polarity are applied to the coordinate windings X 6 and Y 5. Under the total effect of these currents, the ferrite cores 2 will appear in the initial state.

Using a certain switching of the windings from the ignition device in the storing device, the interference from the partially excited ferrite cores will be blocked and will not have any effect on the formation of useful signals in the reading, As a result, the first discharge will read 1 .

Thus, if known (iwrenb would have a ratio of rows and a column of 8: 8, as indicated in the drawing, then the number of bits of such a drive is O, 5, and the proposed drive has two bits, i.e. the number of bits Dov drive is increased four times, which in turn pezhyshaet performance of such drive.
