Abstract
A data storage device coupled to a host device via a predetermined interface includes a memory device, an SRAM, and a controller. The controller is coupled to the memory device and the SRAM. The controller receives a first power mode change request packet requesting to change the data transfer speed of the predetermined interface from a first speed to a second speed via the predetermined interface from the host device, and in response to the first power mode change request packet, the controller determines whether the operation status of the data storage device is busy. When the operation status of the data storage device is busy, the controller determines to reject the request to change the data transfer speed and keeps the data transfer speed at the first speed and does not change the data transfer speed to the second speed.
