Abstract: A method for performing adaptive locking range management, an associated data storage device and a controller thereof are provided. The method may include: receiving a security command from outside of the data storage device, wherein the security command is related to changing an old locking range into a new locking range; obtaining a start Logical Block Address (LBA) and a length value of the new locking range according to the security command; determining whether the start LBA of the new locking range is less than an end LBA of the old locking range, and determining whether an end LBA of the new locking range is greater than a start LBA of the old locking range; and in response to both determination results being true, performing data trimming on any respective non-overlapped portions of the new locking range and the old locking range.

Abstract: A method for performing access management of a memory device and associated apparatus (e.g. the memory device and controller thereof such as a memory controller within the memory device, an associated host device and an associated electronic device) are provided. The method may include: when the host device sends a host command to the memory device, utilizing the memory controller to estimate a completion time of the host command, to generate completion time information corresponding to the completion time; and utilizing the memory controller to send the completion time information to the host device, to allow the host device to perform polling after the completion time to obtain execution result of the host command.

Abstract: The present invention provides a method performed by a secure digital (SD) card supporting both an SD mode and a peripheral component interconnect express (PCIe) mode for initializing the SD card. The method includes: (a) after receiving a first supply voltage through a first voltage supply pin from a host coupled to the SD card, entering the SD mode if the SD card is not in the PCIe mode and a CMD0 command for entering the SD mode is received through a command pin from the host coupled to the SD card; and (b) after receiving the first supply voltage through the first voltage supply pin from the host coupled to the SD card, performing a PCIe linkup process if the SD card is not in the SD mode and a second supply voltage is received through a second voltage supply pin from the host coupled to the SD card. The SD card enters the PCIe mode if the PCIe linkup process succeeds.

Abstract: High-efficiency control technology for non-volatile memory. A controller allocates spare blocks of a non-volatile memory to provide an active block and writes data issued by a host to the active block. The controller further uses the active block as the destination for data transferred from a first source block when there are fewer spare blocks than the threshold amount. When a second source block meets the transfer requirements, the controller uses the active block as the destination for data transferred from the second source block.
