Abstract:
In conventional memory systems, no access control is performed when write-x and datacopy0 are issued. To address this issue, it is proposed to provide access control to these commands by leveraging the mechanism to enforce access control to normal write commands so that the mechanism is also applied to the write-x and datacopy0 commands.
