Abstract
The present invention provides a data storage device including a flash memory, a controller and a delay circuit. The controller receives a read command from a host, reads a first data sector from the flash memory according to the read command, and produces a setting signal according to the maintenance time of the flash memory when the flash memory needs to be maintained. The delay circuit receives the setting signal from the controller, divides the first data sector into a plurality of first sub-data sectors according to the setting signal, and transmits at least one of the first sub-data sectors to the host at a predetermined time interval for extending the busy time of the controller.
