Abstract

A data storage memory has an interface for communications between host computers which communicate over buses with different protocols. The interface detects the protocol of communications from the host computer and changes to match the protocol of the bus. Status registers are read by the host computer to determine the status of the communication between the host and the drive. If repeated reads of the status register are made the interface changes the protocol of the host.
