UNIVERSAL MEMORY ELEMENT WITH SYSTEMS USING THIS ELEMENT, METHOD AND DEVICE FOR READING, WRITING, AND PROGRAMMING UNIVERSAL MEMORY ELEMENT Russian patent published in 2003 - IPC

FIELD: programmable memory elements, their reading, writing, and programming. SUBSTANCE: method for memorizing and retrieving information in phase-transition memory element includes information storage in memory element by transmitting at least one programmed energy pulse to memory material, retrieval of information stored in memory element by supplying additional programmed energy pulses to this element, and counting of mentioned additional pulses required for switching over memory element to low-resistance state. Device for controlling network connectivity in nodal line of neuron network has single location incorporating phase- transition material, two electrodes, control output, signal output, common control and signal output, and neuron network control system. Operation of this device is described by method for controlling interconnection element for varying neuron network connectivity. EFFECT: provision for using such memory elements in cryptography. 21 cl, 16 dwg
