Abstract
A method for fabricating a floating gate memory device comprises using a buried diffusion oxide that is below the floating gate thereby producing an increased step height between the floating gate and the buried diffusion oxide. The increased step height can produce a higher GCR, while still allowing decreased cell size using a virtual ground array design.
