Abstract

The invention relates to a data processing method and a corresponding data storage device. The data storage device includes a memory device and a memory controller. The memory controller configures a predetermined memory block as an active memory block for receiving data from a host device, and updates contents of a sub-region bit table in response to a write operation of the active memory block. The sub-region bit table comprises one or more bits, each bit is associated with one or more sub-regions, and a numerical value of each bit is initially set as a preset value. When the data of a first logical address received from the host device is written into the present memory block, the memory controller determines which sub-region the first logical address belongs to, and sets a value of a bit associated with the sub-region to which the first logical address belongs to a predetermined value different from the predetermined value.

Description

technical field [0001] The invention relates to a data processing method capable of effectively improving the access performance of a memory device and a corresponding data storage device. Background technique [0002] As the technology of data storage devices has grown rapidly in recent years, many data storage devices, such as conforming to the Secure Digital (Secure Digital, abbreviated as SD) / Multi Media Card (Multi Media Card, abbreviated as MMC) specifications, composite flash Memory cards (Compact flash, abbreviated as CF), memory stick (Memory Stick, abbreviated as MS) and extreme digital (abbreviated as XD) specifications, solid state hard drives, embedded multi-media memory cards (embedded Multimedia) Media Card (abbreviated as eMMC) and Universal Flash Storage (abbreviated as UFS) have been widely used in various purposes. Therefore, efficient access control also becomes an important issue on these data storage devices. [0003] In order to assist the access ope...
