Apparatus and methods for programming memory cells responsive to an indication of age of the memory cells

Abstract:

Methods of operating a memory, and memory configured to perform similar methods, may include applying a first plurality of programming pulses to control gates of a plurality of memory cells during a particular programming operation and applying a second plurality of programming pulses to the control gates of the plurality of memory cells during a subsequent programming operation, wherein the first plurality of programming pulses have a particular slope, and wherein the second plurality of programming pulses have a different slope less than the particular slope. Methods of configuring a memory may include characterizing a read window budget for a programming operation of the memory as a function of a programming step voltage for a plurality of memory cell ages.
