Abstract:
A information handling system, comprising:a memory array, wherein the memory array comprises:a number of floating gate tunneling oxide (FLOTOX) transistors, wherein each FLOTOX comprises:a substrate, the substrate having a first source/drain region, a second source/drain region, and a body region, the substrate having a textured surface, the textured surface including an array of microtips, each microtip having a top surface, and wherein the microtips have an average density of 10.sup.12 /cm.sup.2 ;a tunnel oxide layer formed on the textured surface of the substrate, wherein the tunnel oxide layer is deposited using atomic layer epitaxy (ALE);a first conductive layer formed on the tunnel dielectric;an insulator layer formed on the first conductive layer; anda second conductive layer formed on the insulator layer;a number of wordlines, wherein each wordline couples the second conductive layer for a number of FLOTOX transistors;a number of bitlines, wherein each bitline couples the second source/drain region for a number of FLOTOX transistors;a number of sense amplifiers, wherein each sense amplifier couples to select number of the number of bitlines; anda number of sourcelines, wherein each sourceline couples a first source/drain region for a number of FLOTOX transistors;a central processing unit; anda system bus, wherein the system bus couples the memory array to the central processing unit.
