    • The present invention is a multi-phase method, circuit and system for programming non-volatile memory (“NVM”) cells in an NVM array. The present invention may include a controller to determine when, during a first programming phase, one or more NVM cells of a first set of cells reaches or exceeds to first intermediate voltage, and to cause a charge pump circuit to apply to a terminal of the one or more cells in the first set second phase programming pulses to induce relatively greater threshold voltage changes in cells having less stored charge than in cells having relatively more stored charge.
    • 本发明是用于在NVM阵列中编程非易失性存储器(“NVM”)单元的多相方法,电路和系统。 本发明可以包括控制器,用于确定在第一编程阶段期间,第一组单元的一个或多个NVM单元何时达到或超过第一中间电压,并且使电荷泵电路施加到 第一组第二阶段中的一个或多个单元编程脉冲,以在具有较少存储电荷的单元中产生相对较大的阈值电压变化,具有相对较多存储电荷的单元。
