PURPOSE:To store analog information easily by injecting hot carriers to a floating electrode while crossing the energy barrier of an insulating film covering the floating electrode. CONSTITUTION:Electrodes 13, 14 for injecting charges generating hot carriers by a tunnel effect, a control electrode 1 for setting tunnel voltage mounted among the electrodes 13, 14 for injecting the charges and a floating electrode 2 and an insulating film 3 shaped between the control electrode 1 and the floating electrode 2 are provided. Hot carriers are injected to the floating electrode while crossing the energy barrier of the insulating film 3 covering the floating electrode 2. Accordingly, a non-volatile memory in which an analog value is stored easily can be constituted. |
