Programming these is quite straightforward. It basically just involves
applying valid address and data, power supply (5 volts and programming
voltage), and pulsing CE low for some predetermined amount of time, then
reading back the value to make sure it worked. If it didn't work, repeat
the process. If you have more than 25 reps, report an error and abort. For
specifics, check out http://www.amd.com

Good luck,
