Abstract
The present invention facilitates programming of selected floating gate devices while successfully inhibiting the programming of unselected devices, without the need for growing multiple thicknesses of oxides. The preferred embodiment of the present invention utilizes a multiple select gate device. In particular, the select gate device is preferably a dual floating gate device rather than the conventional transistor (or device functioning as a conventional transistor) used in the current Flash memory systems as a select gate device.
