Abstract
A page table method that allows programming of flash memory without corrupting the translation lookaside buffers is described. Flash memory is used to store page tables and other data. In one embodiment of the invention, the page tables are shadowed in random access memory after system bootup to prevent the system from crashing in the event the page tables are accessed while the read only memory is being programmed. In a second embodiment of the invention, the translation lookaside buffers are pre-charged.
