Patent ID: 6914812

Claim:
A floating gate circuit comprising: a) a floating gate for storing charge thereon; b) a first tunnel device formed between said floating gate and a first tunnel electrode, said first tunnel electrode biased by a first voltage during a set mode; c) a second tunnel device formed between said floating gate and a second tunnel electrode, said second tunnel electrode biased by a second voltage during said set mode; d) a first circuit coupled to said floating gate, said first circuit for generating an output voltage at an output terminal; e) a level shift circuit comprising a third tunnel device coupled between said output terminal and said first tunnel electrode, said level shift circuit for generating said first voltage during said set mode; and f) a second circuit for causing said first voltage to be modified as a function of said output voltage, under the control of said level shift circuit, until said floating gate circuit settles to a steady state condition during said set mode.
