Title:
不揮発性半導体記憶装置
Document Type and Number:
Japanese Patent JP4013750
Kind Code:
B2
Abstract:
To provide a nonvolatile semiconductor memory device of a new structure capable of reducing the area of a peripheral circuit by simplifying it.
In the structure of a flash memory, a high energy electron called DAHE is used for writing operation while a high energy hole called DAHH is used for erasing operation. A coupling ratio is adjusted so that the DAHE and DAHH are generated at a single kind of voltage value.
