Abstract
An integrated circuit that includes a first dual-floating gate memory cell having a first floating gate isolated from a second floating gate for storing at least one bit of datum, and a second dual-floating gate memory cell having a third floating gate isolated from a fourth floating gate for storing at least one bit of datum, wherein the first dual-floating gate memory cell and the second dual-floating gate memory cell share a control gate, wherein the second floating gate of the first dual-floating gate memory cell shares an oxide layer with the third floating gate of the second dual-floating gate memory cell, and wherein the oxide layer electrically insulates the second and third floating gates from the control gate.
