Modeling NAND Flash Memories for IC Design

In this letter, we present a compact model of NAND Flash memory strings for circuit simulation purposes. This model is modular and easy to be implemented, and its parameters can be extracted through a simple procedure. It allows accurate simula- tion of NAND Flash memories with a limited computational effort, taking into account capacitive coupling effects which will become extremely important in future technology generations. This model is a very valuable tool for IC designers to optimize NVM circuits, particularly in multilevel applications.
