Abstract :
A new two-step program scheme is proposed for Si nanocrystal memory devices. The new scheme combines one soft Fowler-Nordheim (FN) program at low voltage and one channel-hot-electron (CHE) program. The device characteristics are compared under cycling of FN erasing and three different program methods: FN program, CHE program and the new two-step program scheme. The new scheme not only gives a large memory window, but also has the advantages of low voltage operation, good endurance and data retention characteristics.
