In this paper, we present an experimental procedure to extract the relative capacitive coupling of drain and gate with the floating-gate in a non-volatile memory cell. The method is used to quantitatively assess the increased drain turn-on immunity of discrete-trap memories in comparison with standard Flash. Results show that a large reduction in the relative drain to floating-gate capacitive coupling is obtained by discrete-trap storage, thanks to the low lateral coupling of the storage nodes.

Abstract
In this paper, we present an experimental procedure to extract the relative capacitive coupling of drain and gate with the floating-gate in a non-volatile memory cell. The method is used to quantitatively assess the increased drain turn-on immunity of discrete-trap memories in comparison with standard Flash. Results show that a large reduction in the relative drain to floating-gate capacitive coupling is obtained by discrete-trap storage, thanks to the low lateral coupling of the storage nodes.File in questo prodotto:
