Abstract
A memory protection module includes comparison logic that has a write-once window CSR that stores a memory address range, and window protection logic. The comparison logic receives a memory write transaction, determines a memory address of the memory write transaction, and provides an indication as to whether or not the memory address is included in the memory address range. The window protection logic receives the memory transaction, receives the indication from the comparison logic, allows the memory write transaction to proceed in response to the indication indicating that the memory address is not included in the memory address range, and drops the memory write transaction in response to the indication indicating that the memory address is included in the memory address range.
