(57) Abstract:

The invention can be used in computing when building the law of Ukraine on the cores and is intended for use access memory. The technical result obtained from the compounds of the invention - improving performance, reducing power consumption is achieved by providing the possibility of such formation of the current sample, in which the switching of the selected cores in the States "On" or "I" allows you to record new information in memory one of the pulses, and thereby decreasing the cycle accesses to memory. Reduction of 2 times the power consumption and the performance increase is achieved by reference to the law of Ukraine on the cores, stitched orthogonal windings. Through selected windings of one of the coordinates miss the pulse currents of the sample, the polarity of which corresponds to the recorded information, and the selected windings of the other coordinates miss the pulse currents of appropriate polarity. To simplify control before the implementation of these operations on the selected windings of both coordinates miss the pulse currents of opposite polarity. To do this, in memory of predlozheniya and drive, the drive performed on single-bit storage on the cores that are controlled by respective bits of the input register number. 2 C. p. 1 C. p.

The invention can be used in computing when building memory devices), magnetic cores.

Known methods of recording information in the memory on magnetic cores based on the recording of "O" (reading, zeroing) the first address of the current pulse flowing through windings address, and write "1" current pulses of opposite polarity, the noise on the address and bit windings.

A memory for implementing such methods account consists of the address, input and output bit parts and drive [1]

The disadvantages of such technical solutions are low speed and large power consumption due to the presence of two, separated by time pulse currents of different polarity.

Known method of recording information in memory on the magnetic cores of the closest in technical essence is a method used in a memory, the cores of which are on private hysteresises cycles [2]

The method of entry prot is separated windings, first time pass impulse address (numeric) current of one polarity, amplitude sufficient to fully switch cores on the winding of one coordinate, producing switching all the cores that the coordinates were in the "1" in the zero state and zero confirmation of the condition of the cores of this position, located in "About". Then on the same winding miss the second time, the address pulse of current of opposite polarity amplitude sufficient to switch cores in one state and all other windings coordinates miss the pulse discharge currents, the polarity of which corresponds to the recorded information, for example, when writing "1" then the polarity of the discharge current is the same as the polarity of the address of the current in the core is the addition of address and bit currents), and if it is written "0", the polarity of the discharge current does not coincide with the polarity of the address of the current in the core is the subtraction of the address and bit currents), the amplitude of the bit currents are insufficient to start switching cores.

ZU that realizes this notation consists of the address register, the inputs of the ditch which is connected to one inputs of the elements match, other inputs of which are connected to the input bus "Bit. write" memory output register number, the outputs of which are connected to the output bus memory, and memory, which includes memory matrix on the cores (magnetic drive), bound by a system of orthogonal windings, a circuit for decoding addresses and shapers address current reading (the first time the address pulse input) and write (the second time the address pulse current), the outputs are connected to the inputs of one coordinate (same coordinate windings) magnetic drive, shapers discharge currents entries 1 and 0, the outputs are connected to the inputs of the other coordinates (or other coordinate windings) and playback amplifiers whose inputs are connected to the outputs of the magnetic drive; the outputs of the address register are connected to the inputs of circuits decode address memory, the outputs of the elements matches with the input shapers of the discharge current of the drive inputs of the output register number to the outputs of amplifiers play of the drive, and the inputs of the circuits start shapers address current read and write the drive with input tyres "Read" and "Write" memory, respectively.

The device works createdtime code address, set in the address register, the shapers address current reading in a selected winding of the corresponding coordinates of the magnetic drive is generated the first time a current pulse, which moves all the cores of the selected coordinate of the winding of the magnetic storage device in the zero state. Then use a trigger pulse received on the bus "Write" memory triggers shapers write current in the winding of the magnetic tape drive is formed on the second time a current pulse of opposite polarity; at the same time on the bus "Bit. record ZU served pulses, stimulating the outputs of the respective accepted in the input register number of recordable code elements match; this triggers the shapers bit write "1" and "0" of the drive and all the windings of the other coordinates of the magnetic drive currents are formed bit entry. In those cores in which is written "1" the address and bit currents are formed by switching them in one state ("1"). In those cores that record 0 of the address and bit currents are subtracted, leaving them in the zero state (0).

The disadvantages of such techno cycle time write "0" write "1".

The objective of the invention is to increase speed and reduce power consumption during recording of information in memory on the magnetic cores.

The problem is solved in that in the method of recording in a memory on magnetic cores, stitched orthogonal windings, characterized in that the selected windings of one coordinate matrix storage (magnetic drive) drive pass the pulse current, the polarity of which corresponds to the information recorded on the selected windings of the other coordinates matrix storage drive pass the pulse currents of appropriate polarity (skip pulses of current, the polarity of which corresponds to the recorded information).

To do this in Lou on the magnetic cores consisting of the address register, the input and output registers of the number and the drive, the drive performed on single-bit storage devices that are managed using the corresponding bits of the input register number.

In Fig. 1 is a diagram of the law of Ukraine on the magnetic cores of Fig.2 scheme of the single-bit memory device, and Fig.3 timing diagram of the operation of the memory.

The proposed method of recording information in the memory of which corresponds to a (defined) recorded data (binary code record number).

The proposed memory consists of register 1 address of input register 2 numbers whose inputs are connected to respective input buses ZU; element 31. 32mcoincidence, some outputs of which are connected with the direct and inverse outputs of the respective triggers 41.4mregister 2, and the other inputs connected to the bus 5 polling memory; the output register 6 numbers, the outputs of which are connected to the output bus memory, and the bit drives 71.7mmagnetic cores, the scheme of which is shown in Fig.2, the address inputs are connected to outputs of the register is 1, the outputs to the inputs of the register 6, and inputs "please take" (record "0" and "Record" (record 1) with the outputs of the respective elements 3 matches.

Bit memory 7 memory may be made to any diagram 2D, 3D, 2.5 km E of sampling. In Fig.2 is a diagram of the drive, made by the system matches currents 3D. The drive consists of a storage matrix of magnetic cores (magnetic drive), two devices selection by coordinates X and Y, respectively, each of which consists of circuits decode address (any), address shapers currents "Read" and "Write" managed schemes decode addresses from which you run from p the indicator playback read the signal.

Work one-bit memory (any) simple. When submitting the questionnaire pulse "please take" ("Entry") runs the corresponding code address shapers currents "Read" ("Record") and in the corresponding coordinate windings (one for the X coordinate and one for the Y coordinate) are generated currents (palataki) sampling, switching the selected core is in the zero (single) condition.

In the proposed memory (Fig.1) using pulse received via the bus 5, items 3 matches are produced corresponding to the input code number is passed in register 2 number of polling pulses "please take" and "Record" (on one drive goes one polling pulse) and the corresponding drives 7 device is recorded during one pulse, one or zero information.

Thus, during one pulse for recording new information in memory, which can increase performance of memory and reduce power consumption when writing.

Since in most cases the sampling device drives 7 are performed using transformers (magnetic switch), problems arise associated with a decrease in performance because of the appearance (nakaplivali when multiple records are the same (only "0" or "1") information.

The elimination of this effect is achieved by the fact that pre-run opposite shapers address currents, i.e. the recording of information is performed using two different pulses (performance gain, but a loss in power).

1. The method of recording information in a storage device, magnetic cores, stitched orthogonal windings, namely, that according to selected windings of the magnetic cores of the same coordinates miss the pulse currents account, the polarity of which corresponds to the recorded information, wherein the selected windings of the magnetic cores of the other coordinates miss the pulse currents entries corresponding polarity.

2. The method according to p. 1, wherein the pre-selected windings of the magnetic cores of both coordinates miss the pulse currents accounts with the polarity opposite to the polarity of the pulse currents entries recorded data.

3.
