Abstract
Data storage devices function by communication between a controller and a memory device over a data bus. The memory device can, at times, be busy. Attempting to communicate with the memory device while the memory device is busy causes delays. Holding back communications when the memory device is not busy causes avoidable delays. Correctly predicting the timing of when the memory device is available will reduce delays. An adaptive prediction timer is used that increases the time between communications if a status check of the memory device returns a busy indication, and decreases the time between communications if the status check returns a not busy indication.
