Abstract: The present invention relates to a novel probe set for an isothermal one-pot reaction, and uses thereof and, particularly, provides a method for easily, accurately, and quickly diagnosing molecules, in particular, infection diseases, in the field, the method having a form applicable in the field on the basis of a nucleic acid sequence by using a one-pot reaction composition under an isothermal condition. If a molecular diagnostic platform according to the present invention is used, a target sequence can be quickly and accurately detected. Also, elements (reaction buffer, enzyme) needed in a diagnostic process using the present invention are much more simple and convenient than in a conventional antibody-based diagnosis, and, thus, the diagnostic process can be performed by a non-skilled person, and the sensitivity and speed of diagnosis can be increased, as all reactions are unified at a constant temperature without expensive equipment used in general nucleic-acid-based molecular diagnostic technology, and an amplification process is performed automatically during a reaction process.

Abstract: There is provided an analog-stochastic converter for converting an analog voltage signal into a pulse signal having a corresponding probability. The analog-stochastic converter is implemented using a threshold switching element and a simple logic circuit, thereby reducing a size of the analog-stochastic converter and enabling a low power operation thereof. In addition, in order to update a weight, instead of an analog signal, a probability signal is applied using the above-described analog-stochastic converter, thereby updating a weight in a fully-parallel manner in a synaptic element array having an intersection structure. Accordingly, it is possible to shorten a time for weight update.
