    摘要: A bandgap engineered SONOS device structure for design with various AND architectures. The BE-SONOS device structure comprises a spacer oxide disposed between a control gate overlaying an oxide-nitride-oxide-nitride-oxide stack and a sub-gate overlaying a gate oxide. In one example, a BE-SONOS sub-gate-AND array architecture has multiple strings of SONONOS devices with sub-gate lines and diffusion bit lines. In another example, a BE-SONOS sub-gate-AND architecture has multiple strings of SONONOS devices with sub-gate lines, relying on the sub-gate lines that create inversions to substitute for the diffusion bit lines.

    摘要: A bandgap engineered SONOS device structure for design with various AND architectures to perform a source side injection programming method. The BE-SONOS device structure comprises a spacer oxide disposed between a control gate overlaying an oxide-nitride-oxide-nitride-oxide stack and a sub-gate overlaying a gate oxide. In a first embodiment, a BE-SONOS sub-gate-AND array architecture is constructed multiple columns of SONONOS devices with sub-gate lines and diffusion bitlines. In a second embodiment, a BE-SONOS sub-gate-inversion-bitline-AND architecture is constructed multiple columns of SONONOS devices with sub-gate inversion bitlines and with no diffusion bitlines.
