Title: Non-volatile semiconductor memory and method of driving the same
Inventor: TAKAHASHI KEITA
IPC: H01L29/792
Filed: 2002-07-29
Abstract: PROBLEM TO BE SOLVED: To increase the reliability of a non-volatile semiconductor memory having a floating gate electrode and a control gate electrode and also to enable low-voltage rewriting and reading therein. SOLUTION: Between a source diffusion layer 8 and a drain diffusion layer 9 of a semiconductor substrate 1, a memory transistor and a select transistor are formed side by side via an intermediate diffusion layer 10. The memory transistor comprises a gate insulation film 4 having such a thickness as to allow a tunnel current to flow, a floating gate electrode 5, an interelectrode insulation film 6, and a control gate electrode 7, while the select transistor comprises a gate insulation film 11 and a selection gate electrode 13. By using such a tunnel current that allows electrons to pass through nearly the entire surface of the gate insulation film 4 under the floating gate electrode 5 when removing or injecting electrons from or into the floating gate electrode 5, high reliability and low-voltage rewriting can be obtained.  Furthermore, by providing the select transistor, low-voltage reading is obtained.
