摘要

Reliability studies of localized oxide-nitride-oxide memory (LONOM) devices are presented. The observed reduction in channel threshold voltage as a result of the retention charge loss of a programmed cell is demonstrated in terms of vertical leakage paths. Despite the apparent controversy of charge transport with nitride read-only memory (NROM) devices, the vertical paths are evidently observed via the channel and junction threshold voltage changes, which were monitored using Ⅰ_(ds)-Ⅴ_(ds) curves and gate-induced drain leakage (GIDL) measurements, visualizing the internal status of interface charges and stored charges in a nitride layer.
