Electrically erasable and programmable semiconductor memory

摘要

A first transistor is connected between the gates of select transistors connected to two ends of a memory cell and a select line control circuit. A first gate line is connected to the gate of the first transistor. A first voltage control circuit controls the voltage of the first gate line to turn on or off the first transistor. A second transistor is connected between the control gate of the memory cell and a word line control circuit. A second gate line separated from the first gate line is connected to the gate of the second transistor. A second voltage control circuit controls the voltage of the second gate line to turn on or off the second transistor.
