  • Flash memory with coarse/fine gate step programming
    Patent number: 7057934
    Abstract: A flash memory includes multi-level cells (MLC) that are programmed with a combination of coarse gate voltage steps and fine gate voltage steps. The multi-level cells include floating gate transistors that are programmed by modifying the threshold voltages of the floating gate transistors. Coarse gate voltage steps are used until the threshold voltage any of the transistors being programmed reaches a reference value, and fine steps are used thereafter.
