    摘要: In a nonvolatile semiconductor memory device, there is provided a technique which promotes microfabrication by reducing a thickness of the device as suppressing an OFF current of a polysilicon diode which is a selective element. A polysilicon layer to which an impurity is doped at low concentration and which becomes an electric-field relaxation layer of the polysilicon diode which is a selective element of a resistance variable memory is formed so as to be divided into two or more layers such as polysilicon layers. In this manner, it is suppressed to form the crystal grain boundaries thoroughly penetrating between an n-type polysilicon layer and a p-type polysilicon layer in the electric-field relaxation layer, and therefore, it is prevented to generate a leakage current flowing through the crystal grain boundaries in application of a reverse-bias voltage without increasing a height of the polysilicon diode.

    摘要: A data processing method is performed by an edge device acquiring collected data from a collection target and a first computer capable of communicating with the edge device. The method includes: a first calculation process of, by the edge device, storing the collected data in a secure region to which referring of internally stored information from outside is not allowable and calculating first data which has a data amount less than the collected data and is irreversible in the secure region based on the stored collected data; a first communication process of, by the edge device, transmitting the first data calculated through the first calculation process to the first computer; and a second calculation process of, by the first computer, calculating second data based on the first data transmitted from the edge device through the first communication process.
