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 of the drive's flash memory, and when the flash memory 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. Parameters of the memory operation are then adjusted based on the retrieved bias values, and the memory operation is performed using the adjusted parameters.
