Abstract: Provided is a method of memory access for a memory controller in an integrity monitoring system sharing memory with a host system. The memory access method may include: receiving a memory access command from a local processor of the integrity monitoring system; accessing a system memory of the host system according to the memory access command; receiving data corresponding to the memory access command from the host system; and forwarding the received data to the local processor, wherein the system memory includes a secure area, access to which is allowed when the memory controller receives a memory access command from the local processor. In a feature of the present invention, there are provided a method and apparatus that can monitor integrity of data processed in the host system in a SoC environment.
