MULTI-OPERATING STATE SERIAL ATA DEVICES AND METHODS OF OPERATION THEREFOR

摘要

Methods and SATA devices having more than one operating state suitable for providing efficient command and data transfers over a SATA bus. A SATA device is provided for communicating with a host. The host sends commands to the SATA device and the SATA device sends data to the host in response to the commands being received by the SATA device. The SATA device has a queue of commands received from the host. The SATA device is configured to operate in a first operating state wherein the commands are received by the SATA device and the data are not sent to the host, and a second operating state wherein the commands are received by the SATA device and the data are sent to the host wherein data being sent to the host has priority over receiving commands by the SATA device.

1. A Serial Advanced Technology Attachment (SATA) device for communicating with a host, the host sending commands to the SATA device and the SATA device sending data to the host in response to the commands being received by the SATA device, the SATA device having a queue of commands received from the host, wherein only one of either the commands from the host and the data from the SATA device is sent at a time, the SATA device comprising:
a first operating state wherein the commands are received by the SATA device and the data are not sent to the host; and a second operating state wherein the commands are received by the SATA device and the data are sent to the host, wherein data being sent by the SATA device to the host has priority over commands being received by the SATA device from the host.
