  • Method for programming of a semiconductor memory cell
    Patent number: 6292394
    Abstract: A method for programming an array having a multiplicity of memory cells. The method includes, per cell to be programmed, verifying a programmed or non-programmed state of the cell and flagging those of the cells that verify as non-programmed during one of the verify steps after having previously verified as programmed. A programming pulse having a programming level is applied to the non-programmed cells which are not flagged cells. The steps of verifying, flagging and applying are then repeated until all of the cells verify as programmed at least once. Subsequently, a boost pulse having a boost programming level lower than the programming level is applied to the flagged cells.
