Abstract

The application discloses a memory controller and a method for accessing a memory module. The memory controller is coupled between the memory module and the main controller to control the main controller's access to the memory module, and the memory controller includes: a central buffer, which is coupled to the main controller, for The main controller receives a data access command, and is coupled to the storage module, for providing a modified data access command to the storage module; wherein, the central buffer includes an access command processing module, which is used for processing all processing the data access command to generate the modified data access command; a data buffer coupled to the central buffer for receiving the modified data access command from the central buffer, and coupled to between the main controller and the storage module, for exchanging data between the main controller and the storage module under the control of the modified data access command.

Description

technical field [0001] The present application relates to the technical field of memory, and more specifically, to a memory controller and a method for accessing a memory module. Background technique [0002] In today's computer systems, memory modules provide data access and storage for central processing unit (CPU) operations. With the continuous improvement of the reading speed of the memory module, in order to ensure the signal transmission quality between the CPU and the memory module, the memory module will use a control chip with a buffer function to buffer the operation commands issued by the CPU and the corresponding storage addresses. , and the memory module also has a data buffer that can buffer data in both directions. [0003] However, the existing memory modules operate in a single mode, and only support simple operations such as reading and writing, which limits the functions of the memory modules. Therefore, it is necessary to improve the data access method...
