Problems solved by technology

If you directly copy all the data stored in the old device to the new device, the time spent on the copy operation will be very lengthy due to the large amount of copied data
In addition, after the copy is completed, because the new device stores a large amount of data, including invalid data, the access efficiency of the new device will also be greatly reduced

Embodiment Construction

[0031] figure 1 It is a block diagram showing the system as described in accordance with an embodiment of the present invention. The system can be a data storage system, a computer system or an electronic product system. System 100 can include a host device 110 and a storage device 120. The storage device 120 can include a memory controller 121 and one or more memory devices. According to an embodiment of the invention, the storage device 120 can be in an electronic product or a solid state hard disk connected to the electronic product (SSD). The memory controller 121 can be coupled to the one or more memory devices, wherein the memory device can be a dynamic random access memory (DRAMIC) 122 and flash memory (Flash Memory) shown in the figure. 123, and flash memory 123 can include a plurality of fast flash memory modules. The memory controller 121 can access the DRAM 122 and the flash memory 123 by a corresponding interface. The memory controller 121 also communicates with the h...

Abstract

A memory controller and a data processing method, the data processing method comprising: configuring a predetermined memory space for recording information of valid data of a memory device, the information being used for indicating which logical memory spaces of the memory device have data associated with valid data; and updating the information according to a plurality of instructions received from a host device.

Description

Technical field [0001] The present invention relates to a data processing method, and more particularly to a data processing method of information of the effective data of the memory device in real time. Background technique [0002] Users sometimes have the need to replace the old hard disk or solid state drive (Solid State Drive, Abblast SSD) with a new hard disk or solid state drive. However, the stored data stored in the old device typically contains valid data and invalid data. If all the data stored in the old device directly into the new device, the time spent on the replication operation will be very lengthy due to the amount of data replicated. Further, after the replication is completed, a large amount of data is stored due to the new device, and the accessible data is included, and the access efficiency of the new device is also reduced. [0003] In order to solve the above problems, the present invention proposes a data processing method for improving the performance ...
