1. A system, comprising:
a memory component including a plurality of memory cells; and
a processing device coupled to the memory component and configured to:
determine a program effective time (PET) for programming at least a portion of the plurality of memory cells based on one or more program step characteristics;
compare the determined PET to a target PET;
in response to the determined PET being different than the target PET, determine a change in PET (deltaPET) to adjust the determined PET towards the target PET; and
in response to the determined deltaPET, use a look-up table (LUT) of preconfigured values of changes to concurrently adjust a first program step characteristic and a second program step characteristic of the one or more of the program step characteristics to adjust the determined PET to the target PET, wherein the concurrent adjustment is based upon the preconfigured values of changes associated with the determined deltaPET.
