The essence of the invention lies in the fact that, due to the connections existing in the proposed device, the operating diagrams, the address, the read and write signals are generated from the same quartz oscillator, which is part of the clock generator. Switching from read-out mode to recording mode is carried out by a signal formed from a line-sync external source of the video signal at a point in time when all the control signals of the memory unit are in the inactive state when the control unit has an enable signal and write mode in re-: .1 readout - by signal, power; under similar conditions nz
