Methods for compensating for variations in bit line resistance during sensing of memory cells are described. The variations in bit line resistance may occur die-to-die or plane-to-plane on the same die. In some embodiments, for each die or memory plane on a die, a plurality of bit line read voltages associated with a plurality of zones may be determined based on sensing criteria. The sensing criteria may comprise a number of fail bits. Each zone of the plurality of zones may be associated with a memory array region within a die or memory plane. Prior to performing a read or verify operation on a group of memory cells, a bit line read voltage used during sensing of the group of memory cells may be determined based on the plurality of bit line read voltages and a zone associated with the group of memory cells.
