Many features of flash memory are covered by patents. Many, if not most of the patents are held either by SanDisk or its president, Harari. New patents are being granted regularly. In addition, a second generation of flash memories that use encryption to prevent unauthorized copying are being developed, with SanDisk again having an important, though not exclusive place in this area. There are many characteristics about the PROCESS of reading and writing that are patentable. It is likely that some of the less sophisticated flash memory designs will become commodities in a few more years. If there is a parallel here with other kinds of chips, the parallel would be closer to ASICS instead of DRAMS.
