Abstract
A method for programming a mixed nonvolatile memory array having a plurality of mixed memory cells, wherein each mixed memory cell includes a depletion mode memory cell and an enhanced mode memory cell. The method comprises steps of programming the enhanced mode memory cell in a way of channel hot carrier and programming the depletion mode memory cell in a way of band-to-band tunneling hot carrier.
