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.

Method to prevent corruption of page tables during flash EEPROM programming

A method for random track playback is presented. A table base value is used to adjust entries in a pseudo-random table stored in read-only memory. A search start offset is used to select a starting point in the adjusted pseudo-random table. Entries before the starting point are effectively wrapped to the end of the pseudo-random table. A playable track, located in the adjusted, wrapped pseudo-random table, is then selected and played.
