Abstract:
An apparatus is provided that includes a control circuit coupled to a plurality of non-volatile memory cells. The control circuit is configured to perform a program-verify iteration on a first set of the non-volatile memory cells in a plurality of program loops, determine that the first set of the non-volatile memory cells passes verification to a particular programmed state in a first number of program loops, determine a first voltage based on the first number of program loops, add an adaptive voltage offset to the first voltage to obtain a second voltage, and program a second set of the non-volatile memory cells in a plurality of program loops using the second voltage. The adaptive voltage offset varies as a function of temperature.
