"We have been forced to narrow the claims in order to distinguish the Norris Voice recorder from the Sharp Voice recorder. "

They have not been force to narrow anything.....the only issue happening for the patent vs prior art dates involved ..are in comparing...who published related explanations first in 1993 vs 1994 for the questions raised by the defendants that initiated the re-exam.....and has nothing to do with being out dated technology or not.

" it has a disadvantage in that MOSFETs are leaky,"

I beg to differ...metal oxide semiconductor field effect transistors are momentary issues, or switches....

They do way more with them than controlling the flash memory VPP /VCC and will continue to control whatever issues are involved in writing to, or flashing the memory.
