The present invention provides a susceptor power-interface assembly which is used for a chamber process module that includes a power supply, a process chamber and a susceptor, wherein the susceptor includes a susceptor shaft penetrating a bottom of the process chamber and a susceptor base on which a wafer is disposed for the process. In one embodiment, the position of the front wheels and the vehicle speed is sensed. An abusive rocking maneuver is detected when the driver commands at least a specified number of successive range shifts during a predetermined time interval, and the speed and torque limitations are imposed until range shifting is discontinued for at least a calibrated period of time. An address range is determined that excludes at least the addresses currently storing functional data. By permitting each of a plurality of portions of a memory array of the memory device to be assigned a corresponding memory cell density determined through an evaluation of those portions of the memory array, better performing portions of the memory array may not be hindered by lesser performing portions of the memory array.
