Patent ID: 7102188

Claim:
An Electrically Erasable and Programmable Read-Only-Memory (EEPROM) cell of a first polarity type comprising the following: a field effect transistor of the first polarity type comprising: a bulk terminal comprising a first well of a second polarity type opposite the first polarity type, wherein the first well is shared by a first plurality of other EEPROM cells; a gate terminal comprising a conductive layer formed over the first well; a first dielectric layer disposed between the gate terminal and the first well, wherein the first dielectric layer is a tunneling dielectric layer; a source terminal of the first polarity type disposed within the first well; and a drain terminal of the first polarity type disposed within the first well; and a capacitor comprising: a first terminal electrically connected to the gate terminal of the field effect transistor; a second terminal comprising a second well of the second polarity type underneath the first terminal, the second well being shared by a second plurality of other EEPROM cells; and a second dielectric layer disposed within the first terminal and the second terminal of the capacitor.
