SU118658A1 - The method of reading information from the system of storage transflyuktorov - Google Patents

Description

The methods of reading information from matrix thia memory devices on transfluctors (current coincidence method or direct selection method) have limited speed and partial memory loss after a read cycle, which necessitates subsequent reheparation of information in the transfluctor, and require cumbersome instrumentation.

In the proposed method, reading the information from the selected matrix transmitter without its resolution is performed by the fact that two odnopolis impulses are fed through one of the wires of the two-coordinate matrix firmware system, between which the selected transfluxor passes through the first wire, a current pulse of another numbering and a strobe pulse, slightly lagging in time from the second pulse of the first wire, to the amplifier gate, which receives read pulses.

In this case, depending on the state of the transfluctor determined by the recording system, the read wire will have a large signal, which corresponds to the "1 (transfluctor unlocked) recording, or no signal will appear, or there will be a small signal that corresponds to the recording “O (transflyuktor blocked).

The blocked core state of the core material is such that a positive pulse through wire 1 (see Fig. 1) or a negative pulse through wire 2 does not significantly change (i.e., in direction) the magnetic flux in jumpers 3 and 4 holes 5 of the traf fi cator 6, i.e. the induced flows coincide in direction with the residual saturation flow in jumpers 3 and 4. Consequently, in reading wire 7, the emf will be induced only slightly, or there will be no impulse. If a positive pulse through the wire / causes a magnetic flux in the core, the inverse of the residual induction vectors in

bridges 3 and 4, the material around hole 5 will peremagnitits. If further along the wire 2 to give a negative impulse, then the material around the opening 5 will re-magnetize again and a significant impulse will appear on the wire 7. Since a positive current pulse can be chosen much larger than a negative one, then the emf em. And the magnetism will be much longer, and the duration will be much less. In FIG. 2 shows a diagram of a matrix type memory device. The read wire 7 penetrates all matrix transfluctors 6, signals from it are fed to the read amplifier valve 8, which also receives a strobe pulse 9, which is slightly lagging behind the leading edge of the second pulse X, i.e. only the second current of the X coordinate. To select a core from the matrix, a wire is selected using the decoder W and two current pulses are sent on it, similarly, the decoder 11 selects the desired UI wire and sends a negative current pulse. Subsequently, everything is determined by the state of the selected transfluctor.

Subject invention

A method for reading information from a system of memorized transfluctors connected to a two-coordinate grid, characterized in that, in order to read information from only one selected transfluctor without destroying it, two single-pole current pulses are sent to the transfluxor by one of the required coordinate wires by applying these pulses to another required wire, perpendicular to the first one, a current pulse of another polarity is supplied, and a gating pulse is fed to the second wire during the supply through the first wire from unipolar pulses.
