Hello, Forgive this slightly off-topic question: The electric field of the trapped electrons adds to the electrons in the floating gate, lowering the window between threshold voltages for zeros vs ones. Dara are algorithms coded into the programmers to hit the EPROM with the appropropriate voltages for specific time periods.
Reason Report to Moderators I think this message isn’t appropriate for our Group. During storage, the electrons injected into the floating gate may drift through the insulator, especially at increased sneet, and cause charge loss, reverting the cell into erased state.
Most new ones withwrite cycles, before data transfers get iffy.
Electronic Inventions and Discoveries: No contracts, No fees, No Kidding! Previous 1 2 You won’t get anywhere without a data sheet for exactly the parts you have, and even then it’s a lot of work to make a programmer that does the job correctly.
If the cycle limit is intended to guard against stray write events, engineering it to be usable with systems that run at slow clock speeds should have been trivial and would have improved usability.
A chip; writing and erasing are accomplished by providing a single volt pulse. It’s easy to find info on the 28C See Section 6 for more information. Number one rule of experimenting is to alway be sure to identify off spec parts to avaoiod re-using them as good ones. Intel is com m itted eepeom the technology of. First hit on google: What do I need to do, in order to write data to the or 28C16?
EPROM Technical Data
To go even more off-topic The 1us maximum write pulse time seems really weird, since many processors would eeorom extra circuitry in order to meet that spec. United States Patent and Trademark Office.
I have one of those, it works great. What’s the deal with the ? Archived from the original on September 29, In other words, it uses tunnel junction mechanism.

But FLOTOX’ s theoretical basis is Fowler—Nordheim tunneling hot-carrier injection through a thin silicon dioxide layer between the floating-gate and the substrate. During rewrites, the gate oxide in the floating-gate transistors gradually accumulates trapped electrons.
Sign up using Facebook. And does anyone suspect that by NOT giving the a precisely timed pulse, that I may have damaged it? I’ve never used the Willem Programmer, I don’t sell it, etc.
These use from 1 to 4 device pins and allow devices to use packages with 8-pins or less. Microelectronic Engineering, Rochester Institute of Technology. Digest of Technical Papers. The theoretical basis of these devices is Dtaa hot-carrier injection.
