SEMICONDUCTOR STORAGE DEVICE, ITS MANUFACTURING METHOD AND OPERATING METHOD, AND PORTABLE ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To realize the scale-down and increased capacity of a memory in a semiconductor storage device, which consists of an element having a function, which converts a change in the charged quantity into a current quantity. SOLUTION: A semiconductor storage device and a portable electronic apparatus having the semiconductor storage device comprises: a first conductivity type region formed in a semiconductor layer; a second conductivity type region formed in the semiconductor layer in contact with the first conductivity type region; a memory functional element disposed on the semiconductor layer across the boundary of the first and second conductivity type regions; and an electrode provided in contact with the memory functional element and on the first conductivity type region via an insulating film. Scale-down and high-integration are implemented by constituting the memory cell of substantially one device. COPYRIGHT: (C)2005,JPO&NCIPI
