Abstract
An integrated circuit has a high voltage area, a logic area and a memory array for forming a system on a chip that includes linear, logic and memory devices. The memory array has floating gate transistors disposed in a triple well structure with a raised drain bit linesubstantially vertically aligned with a buried source bit line. The memory array separates the columns with deep trenchesthat may also be formed into charge pump capacitors.
