This invention is provided with a memory protection unit for controlling access to a memory region from virtual computers.

A data processing system (2) includes memory protection circuitry (10) storing access control data for controlling accesses to data at memory addresses within a main memory (16).

Embodiments of the present invention provide an approach for memory protection at a level of granularity above a "page" level (e.g., enhancing the protection provided by a memory key-based system).

An integrated-circuit device (1) comprises a processor (7), memory (13) for storing executable code, and memory protection logic (9).

A method, system, and program key-controlled object-based memory protection are provided.

The region selection logic is operable to select a memory protection region that includes the address of a target memory access request from a system initiator (e.g., 122, 138).

In order to protect the operating system of a sensor node, coarse-grained memory protection is provided by creating and enforcing an application fault domain in the data memory address space of the sensor node.

The subject of the invention is a method of protecting a digital memory against permanent and transient errors and a related device.

A memory protection system in a multi-tasking system for preventing a currently running application from writing data to a memory segment storing data for a second application.

Said program-controlled unit is characterized in that it contains a memory protection device, which ensures that the contents of the memory, or a specific part of the latter can no longer be modified.

A memory protection unit (MPU) is integrated (1) between the at least one master unit and the network-on-chip bus system.
