Disclosed is an apparatus and method for adjusting operating parameters in a storage device. A controller in a solid state drive monitors current operating conditions for blocks of memory used to store data in the drive. When a block has been subjected to a predetermined number of program/erase cycles one or more stored bias values are retrieved from a storage location based on the wordline(s) associated with a current memory operation. The one or more parameters of the memory operation are then adjusted based on the one or more stored bias values, and the memory operation performed on the block of memory cells using the adjusted parameters.
