Abstract
A NAND flash memory controller can adjust its processing power according to a host speed and thereby save energy. The controller includes: a host speed estimation module estimating the host speed according to a first total data amount of the host's M first I/O command(s) received by the controller within a first period of time, the host speed correlating with the host's demand for access; a controller speed estimation module estimating a controller speed according to a second total data amount of the host's N second I/O command(s) completed by the controller within a second period of time, the controller speed correlating with the processing power of the controller; a speed decision module generating a decision result according to the relation between the host speed and the controller speed; and a speed adjustment module adjusting or maintaining the processing power of the controller according to the decision result.
