ABSTRACT:
A random number generating device includes a semiconductor device including a source region, a drain region, a channel region provided between the source region and the drain region, and an insulating portion provided on the channel region, the insulating portion including a trap insulating film having traps based on dangling bonds and expressed by Six(SiO2)y(Si3N4)1-yMz(M is an element other than Si, O, and N, x≧0, 1≧y≧0, z≧0, the case where x=0 and y=1 and z=0 is excluded), conductivity of the channel region varying randomly depending on the amount of charge caught in the traps, and a random number generating unit connected to the semiconductor device and generating random numbers based on a random variation in the conductivity of the channel region.
