Abstract

A method for fabricating floating body memory cells (FBCs), and the resultant FBCs where gates favoring different conductivity type regions are used is described. In one embodiment, a p type back gate with a thicker insulation is used with a thinner insulated n type front gate. Processing, which compensates for misalignment, which allows the different oxide and gate materials to be fabricated is described.
