Abstract
A storage device optimizes interface training between a controller and a memory device. The memory device includes at least one die on which data is stored. The controller categorizes process, voltage, and temperature (PVT) values into zones and executes an initial calibration on each zone using categorized values assigned to each zone. The controller obtains calibration data for the zones from the initial calibration and stores the calibration data. When the controller determines that an interface training is triggered, the controller performs a subsequent calibration. During the subsequent calibration, the controller retrieves the calibration data and applies the retrieved calibration data to align a data signal with a clock signal and to perform normal operations on the storage device at a current PVT setting.
