A novel 2-bit/cell MONOS memory device with a wrapped-control-gate structure that applies source-side hot-electron injection

Abstract

We have proposed a novel 2-bit/cell MONOS memory structure that features a wrapped gate. Programming and erasing are by source-side hot-electron injection and hot-hole injection, respectively. With this device, programming speeds <1 /spl mu/s with a programming current <2 /spl mu/A//spl mu/m, and erasing speeds <10 /spl mu/s have been achieved.
