Title: Stochastic voltage comparing element
Inventor: UEDA MICHIHITO
IPC: H01L29/06
Filed: 2008-05-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a stochastic voltage comparing element solving such problems with a stochastic voltage comparing element in the conventional art that since only one trial of stochastic action is allowed for one action, it is necessary to return to the initial state many times for obtaining a statistic result, and preparations to the comparing action are very cumbersome as the problem of the element concerning the structure.  <P>SOLUTION: According to this stochastic voltage comparing element, similarity of two input voltages is stochastically detected by detecting a change in the electric potential of an electrode in the lowest downstream as the result of a method in which electrons are stochastically passed through a two-dimensional tunnel structure, due to the energy of thermal noise by injecting electrons into a group of fine conductors arranged two-dimensionally or three-dimensionally which mutually allow tunneling of electrons, in a state in which two input voltages to be compared are capacitively coupled to the group of fine conductors; and further, voltages are capacitively coupled to the group of fine conductors from the other plurality of voltage sources so as to provide a potential gradient to the group of fine conductors. According to the present invention, stochastic comparison operation results can be continuously obtained by continuously injecting electrons into the group of fine conductors and a statistic processing can be performed according to a simple procedure.  <P>COPYRIGHT: (C)2010,JPO&INPIT
