Embodiment Construction

[0013] Certain terms are used throughout the specification and following claims to refer to particular elements. It should be understood by those skilled in the art that hardware manufacturers may use different terms to refer to the same element. This description and the following claims do not use the difference in name as the way to distinguish components, but the difference in function of the components as the criterion for distinguishing. The "comprising" mentioned throughout the specification and the following claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" here includes any direct and indirect electrical connection means, therefore, if it is described in the text that a first device is coupled to a second device, it means that the first device can be directly electrically connected to the The second device, or indirectly electrically connected to the second device through other devices or connection ...

Abstract

The invention provides a method for accessing a storing device and a relevant control circuit. The storing device comprises a first storing unit and at least one second storing unit. The method comprises the following steps of: generating a plurality of defect block lists of a plurality of storing units and setting a favorable block which corresponds to the defect block and can be normally operated in each second storing unit into a replacement block according to at least one defect block indicated by the defect block list corresponding to the first storing unit; and then generating a corresponding mapping result according to the defect block list of each second storing unit and each replacement block and accessing the storing device according to the defect block list corresponding to thefirst storing unit and the mapping result corresponding to each second storing unit.

Description

technical field [0001] The present invention relates to a defective block management method and a related control circuit, in particular to a defective block management method and related circuit for a storage device including multiple flash memories such as a multi-channel solid-state hard drive. Background technique [0002] Various storage devices composed of flash memory have gradually become popular in embedded systems and portable devices. When people have higher requirements on the capacity and performance provided by storage devices, the development of flash memory devices is also indirectly driven. Finally, flash memory devices gradually replace the use of existing storage devices (such as traditional hard disks) in various fields. A development trend that is in full swing and is becoming clear is Solid State Drive (SSD), which is a large-capacity storage device composed of flash memory and is positioned to replace traditional hard disks. Compared with the well-dev...
