Floating Gate devices are the basic building blocks of Semiconductor Nonvolatile Memories EPROM EEPROM Flash . Among these Flash are the most innovative and complex devices. The strategy followed developing this new model allows to cover a wide range of simulation conditions making it very appealing for device physicists and circuit designers. Keywords compact model nonvolatile memory floating gate reliability circuit design. 1 INTRODUCTION Flash Memories are one of the most innovative and complex types of high-tech nonvolatile memories in use today see for example 1 . Since their introduction in the early 1990s these products have experienced a continuous evolution from the simple first ones to emulate EPROM memories to the extreme flexibility of design application in today products. In the memory arena Flash memory is the demonstration of the pervasive use of new electronic applications in our lives exploiting this flexible and powerful memory technology either as a stand-alone component or embedded in a product. Flash are not just memories they are complex systems on silicon they are challenging to design because a wide range of knowledge in electronics is required both digital and analog and they are difficult to manufacture. Physics chemistry and other fields must be integrated and conditions must be carefully monitored and controlled in the manufacturing process. Compact Models
