    摘要: A device includes a semiconductor substrate, source and drain regions in the semiconductor substrate, a channel region in the semiconductor substrate between the source and drain regions through which charge carriers flow during operation from the source region to the drain region, and a drift region in the semiconductor substrate, on which the drain region is disposed, and through which the charge carriers drift under an electric field arising from application of a bias voltage between the source and drain regions. A PN junction along the drift region includes a first section at the drain region and a second section not at the drain region. The drift region has a lateral profile that varies such that the first section of the PN junction is shallower than the second section of the PN junction.

    摘要: A multiple time programmable nonvolatile memory device having a single polysilicon memory cell includes a select transistor and a bitcell transistor. The bitcell transistor has asymmetrically configured source, drain, and channel regions including asymmetrically configured source-body and drain-body junctions. Compared with the drain-body junction, the impurity concentration gradient of the source-body junction is more gradual, which may significantly improve program disturb immunity. The bitcell transistor gate may be connected to an electrode of a coupling capacitor, but may be otherwise floating or Ohmically isolated. The floating gate of the bitcell is protected by a dielectric layer for potentially improved data retention.
