  • Memory cell having hot-hole injection erase mode
    Patent number: 4742491
    Abstract: A single component electrically erasable memory cell is disclosed. A floating gate MOSFET having a relatively short channel is triggered into a snap-back mode positive feedback biasing mechanism. Hot-hole injection onto the floating gate during the snap-back mode neutralizes any charge stored there to represent a data bit.
