Modeling of Threshold Voltage Shift by Neighboring Transistors for Macaroni Channel MOSFETs in Series

In this article, we introduce a model to calculate the threshold voltage of the victim transistor attacked by the neighbor transistors with a macaroni structure. Using this model, we investigate the shift of the victim threshold voltage to get insight into the interference effect of NAND cells in a string with different structural parameters and biases. The fitting between simulations and calculations confirms the validity of these models.
