SU382148A1 - UNIT FOR MONITORING THE SELECTION OF ADDRESS IN MEMORIZING - Google Patents

Description

one

A block is known for controlling the selection of an address in a memory device, which contains magnetic cores, one part of which is stitched with coordinate X, and the other with coordinate Y, connected to the memory storage device, the address register and output memory.

The disadvantage of the known block is its complexity.

The described block for controlling the selection of an address in a memory device differs from the known one in that each magnetic core is stitched with two busbars, some of which are connected respectively to the unit and zero outputs of the address register of the same name, and the others through diodes to the output bus.

These differences simplify the device.

The drawing shows a block diagram of the proposed unit.

The block contains a mag) 1-bit cores / and the address register 2. One of the magnetic cores is stitched with coordinate 3 (X), and the other with coordinate buses 3 (jY) connected to storage drive 4 of the storage device. The block also contains address 5 decoders, output bus 6, readout lines, penetrating the core

1 in the forward direction 7 n in the opposite direction 8, one ends of which are connected respectively to the unit 9 n to zero 10 outputs of the same name register of address 2, and the other ends through diodes 11 are connected to the output bus 6.

The device works as follows. When writing information to the address register

2 one of the outputs 9 of each discharge (single) sets the voltage

equal to zero, and on the remaining outputs of 10 (zero) equal - 2E. During the readout, the current flowing through the corresponding A and-U coordinate buses 3 induces voltage pulses of amplitude E of positive polarity in readout 8, connected to zero outputs of address register 2, and negative polarity to readout 7 connected to single outputs 9 address registers. In this case, the diodes 11 connected via read lines 8 with zero outputs 10 of the address register 2 propose 1) 1 are locked with a potential of 2 U, and the diodes 11 connected to the single outputs I form a matching circuit.

If the device is working properly during the read cycle, there must be a negative impulse on the output bar 6.

If at least in one category there is no

matching the outputs of the address register with the polarity of the signals induced by the coordinate buses appears a polishing signal n: and the output bus 6, indicating a malfunction of the circuit.

Subject invention

The unit for controlling the choice of address in the jamming device, contains; and magnetic cores, one part of which is stitched

X, and the other, x .u, connected to the drive of the zomnoyayushey device, the address register and the output bus, characterized in that

that, in order to simplify the device, each magnetic core will lose by two read lines, one ends of which are connected respectively to the typical and zero outputs of the address register of the same name,

and the others through diodes iodo1 are unbound to the output bus.
