Advanced SPICE modeling for program inhibit operation in NAND flash memories

In this paper, a compact SPICE model of NAND strings especially for program inhibit operation is proposed. With the addition of the 2
^nd
-order capacitances and GIDL current, the capacitive boosting with Vpgm and Vpass, and the potential lowering due to GIDL current generated at GSL edge can be well considered in the model.
