Abstract: A data storage device includes a memory device and a memory controller. The memory device has a corresponding total storage capacity and includes multiple memory blocks. The total storage capacity is set to a maximum storage capacity provided by the memory blocks by default. The memory blocks include one or more predetermined memory blocks configured as a buffer to receive data from a host device. The memory controller is coupled to the memory device to access the memory device. In response to setting of a maximum amount of write data, the memory controller determines a value of the total storage capacity according to the maximum amount of write data, and determines a number of said one or more predetermined memory blocks according to the value of the total storage capacity and the maximum storage capacity.

Abstract: A data storage device including a non-volatile memory and a micro-controller is provided. The non-volatile memory includes a first block and a second block, wherein the first block stores firmware code. The micro-controller writes one predetermined string into the second block before an execution of the firmware code, and determines whether there is more than one predetermined string in the second block. In response to there being no more than one predetermined string in the second block, the micro-controller allows the execution of the firmware code and erases the predetermined string in the second block upon successful completion of a prerequisite procedure during the execution of the firmware code. In response to there being more than one predetermined string in the second block, the micro-controller does not allow the execution of the firmware code.

Abstract: A method for performing initialization in a memory device, the associated memory device and the controller thereof, and an associated electronic device are provided. The method may include: after a non-volatile (NV) memory within the memory device is powered on, searching for an empty-memory indicator in the NV memory, wherein the empty-memory indicator is applicable to determining whether the NV memory is empty; and according to whether the empty-memory indicator is found or not, selectively skipping or performing a program code search in the NV memory, to complete an initialization process, wherein the initialization process includes at least one initial setting of the memory device, and if the empty-memory indicator is found, the program code search is skipped, otherwise, the program code search is performed.
