Abstract
A multi-value single electron memory using a multi-quantum dot, in which the floating gates (FG) of a EEPROM or a flash memory are formed to act as two quantum dots, and the two quantum dots are applied to multi-value memories, and a driving method of the multi-value single electron memory, are provided. Thus, a multi-value memory can be realized using two quantum dots. Also, an ultra-highly integrated memory of 1 Tb or greater can be realized without encountering a physical limit such as a short channel effect (SCE) caused by scaling down MOSFETs, in contrast to other memories.
