Abstract
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. The memory protection system transmits m upper address defining a memory segment of the currently running application to the memory from a memory register. The memory protection system detects when a currently running application generates an invalid address and disables the data operation to prevent the corruption of data in a memory segment storing data for the currently running application. The system verifies that the m upper address bits in the memory register after the application is completed are equal to m upper address bits of the memory segment of the completed application.
