Abstract: A circuit for controlling a memory includes a frequency parameter generator, a clock generator and a memory controller. The frequency parameter generator generates at least one frequency control signal. The clock generator, coupled to the frequency generator, increases or decreases the frequency of a clock signal by a multiple number of times according to the frequency control signal, such that the frequency of the clock signal is adjusted from an initial frequency to a target frequency. The memory controller, coupled to the clock generator, receives the clock signal and controls the memory according to the clock signal.

Abstract: A method for preheating an electronic system when booting in an environment with low temperature and an apparatus using the same are provided. The electronic system includes at least a processor, at least a first controller, and at least a second controller. The method includes: the first controller checking whether the initialization of the second controller is successful or not after the electronic system boots, wherein the first controller include a basic input/output system; entering a preheating mode when the initialization of second controller has failed, wherein in the preheating mode, the processor is powered continuously and a turbo function is enabled, so as to provide a heat energy for heating the electronic system; and stopping the preheating mode and rebooting the electronic system.

Abstract: An electronic storage device and a data protection method are provided. The electronic storage device is electrically connected to a host, and stores data of the host. The data protection method includes the following steps: providing a backup battery where the backup battery is configured inside the electronic storage device to provide electric power for an operation of the electronic storage device when the host does not provide electricity to the electronic storage device; setting a time setting value; transmitting a login event to the electronic storage device; and the electronic storage device determines whether to protect stored data in the electronic storage device according to the time setting value and the login event, wherein if a determination result is affirmative, the electronic storage device protects the stored data.
