Soi cmos structure having programmable floating backplate

摘要

SOI CMOS structures having at least one programmable electrically floating backplate are provided. Each electrically floating backplate is individually programmable. Programming can be performed by injecting electrons into each conductive floating backplate. Erasure of the programming can be accomplished by tunneling the electrons out of the floating backplate. At least one of two means can accomplish programming of the electrically floating backgate. The two means include Fowler-Nordheim tunneling, and hot electron injection using an SOI pFET. Hot electron injection using pFET can be done at much lower voltage than injection by tunneling electron injection.
