Hi
Even faster would be to use a CMOS RAM and
a battery. No special voltages or special
write sequences.
Battery == bad. Use FRAM. It's just like RAM except it retains it's
contents when power's off. Comes in x8 and x16 varieties.

http://clk.atdmt.com/GBL/go/171222986/direct/01/ I have one fo them and it is getting old
burning it, testing the device, erasing it, and burning
different code into it, lather rinse repeat.
Time to get (or build) an EPROM
emulator?
Build a FLASH-EPROM to EPROM adapter socket?
(As erasing a FLASH-EPROM is faster then erasing a EPROM and doesn't
need a UV lamp.)
