Abstract

The invention discloses a memory controller and a method for accessing a memory module. The memory controller is coupled between the storage module and the main controller to control access of the main controller to the storage module. The memory controller includes: a central buffer coupled to the main controller for receiving a data access command from the main controller and coupled to the storage module for providing a modified data access command to the storage module. The central buffer comprises an access command processing module, and the access command processing module is used for processing the data access command to generate the modified data access command; and a data buffer coupled to the central buffer, used for receiving the modified data access command from the central buffer, coupled between the main controller and the storage module, and used for interacting 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 field of memory technology, 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 memory module reading speed, in order to ensure the signal transmission quality between the CPU and the memory module, the memory module will use a control chip with buffering function to buffer the operation commands issued by the CPU and the corresponding storage address And the memory module also has a data buffer that can buffer data in both directions. [0003] However, the existing memory module has a single operation mode and only supports simple operations such as reading and writing, which limits the functions of the memory module. Therefore, it is necessary to improve the data access method of the existing mem...
