Abstract

The invention discloses a buffer memory as well as an apparatus and a method used for controlling internal memory data access. The buffer memory comprises a central cache and a data cache, wherein the central cache is coupled to a memory interface through a command/address channel to receive a command/address signal; the central cache is configured to detect whether the command/address signal received by the central cache belongs to a predetermined address space or not and generate a secure reading/writing signal when the command/address signal belongs to the predetermined address space; the data cache is coupled between the memory interface and a storage module to cache data between the memory interface and the storage module; and the data cache is configured to store reference data, compare the cached data with the reference data in response to the secure reading/writing signal, and determine whether the interaction of the cached data between the storage module and the memory interface is limited or not according to a comparison result of the cached data and the reference data.

Description

technical field [0001] The present application relates to the technical field of memory, and more particularly, to a buffer memory with a data access control function and an apparatus and method for controlling data access in an internal memory. Background technique [0002] The rapid development of Internet technology enables network devices such as computers and mobile terminals to connect and communicate with each other. Through these interconnected network devices, people can obtain information very conveniently. However, while facilitating access to information, data and information security issues have become increasingly prominent. Networked devices are vulnerable to accidental or malicious attacks from unauthorized external devices, resulting in the destruction, disclosure or alteration of internal data. [0003] Therefore, it is necessary to improve the existing computer or other electronic equipment to improve its data security. SUMMARY OF THE INVENTION [000...
