I suspect the programming method may depend on the manufacturer and type
of device.  For example, I found documentation on Intel's site for their
FLASH memory devices that explains in great detail how to write, erase,
read, etc. from the device.  Right out there in the open, where anyone can
see it!! ;-)  You'll have to see who manufactured your FLASH device, then
check the manufacturer's web site for the data sheet or other
documentation that will detail how to erase & program the chip.

The most exciting phrase to hear in science, the one that heralds new
discoveries, is not "Eureka!" (I found it!) but "That's funny ..."
