Abstract: A memory management system, such as a virtual memory manager that manages a virtual memory space that includes volatile memory (e.g. DRAM) and non-volatile memory (e.g., flash memory) creates a reserved portion of memory in the volatile memory for at least one user application in one embodiment, and that reserved portion can also store content that it restricted to read only permission within the non-volatile memory.
