Abstract
Methods and apparatus are provided for programming multiple program values per signal level in flash memories. A flash memory device having a plurality of program values is programmed by programming the flash memory device for a given signal level, wherein the programming step comprises a programming phase and a plurality of verify phases. In another variation, a flash memory device having a plurality of program values is programmed, and the programming step comprises a programming phase and a plurality of verify phases, wherein at least one signal level comprises a plurality of the program values. The signal levels or the program values (or both) can be represented using one or more of a voltage, a current and a resistance.
