Magnetic tape Hard disk drive. The A, like thehas fast read access speeds allow ingparameter storage never before possible.


Thanks for the answer. The manufacturers usually specify the maximum number of rewrites being 1 million or more. 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 shet trivial and would have xheet usability.

Most NOR flash memory is a hybrid style—programming is through hot carrier injection and erase is through Fowler—Nordheim tunneling. I’ve never used the Willem Programmer, I don’t sell it, etc.

Sign up or log in Sign up using Google. The theoretical basis of these devices is Avalanche hot-carrier injection. The address needs to be held for an entire write cycle, so any dynamic latches would need to be able to deal with that. adta


The can be easily erased and reprogrammed on a byte basis. Basics of Nonvolatile Semiconductor Memory Devices.

An running at 3. Egg on my face.

EEPROM, slightly O.T.

Electronic Inventions and Discoveries: A needed a write pulse longer than uS ,nSbut shorter than 1mS 1,nS. And does anyone suspect that by NOT giving the a precisely timed pulse, that I may have damaged it?

What am I missing here? However, if you are looking to program EEPROMs, you may get good ideas from the Willem programmer, as it seems to be open-source of some variety. D to be more accurate: Most sane people don’t spend their time building clocks with antiquated technology!

Back when I just got started in the electronics business, I was working as tech and general slave. It depended on manufacturer.

Siemens Forschungs und Entwicklungsberichte. I am just curious, but. Got away without needing a pulse. I have one of those, it works great. Otherwise, you can write single bytes to it, by pausing after each byte. The new topic will begin with this message.

This meant they could not work down to DC the lowest freq of write cycle possible. There is no clear boundary dividing the two, but the term “EEPROM” is generally used to describe non-volatile memory with small erase blocks as small as one byte and a long lifetime typically datx, cycles.


As is described in former section, old EEPROMs are based on Avalanche breakdown -based hot-carrier injection with high reverse breakdown voltage. Writing was a bit different. Two E’s instead of one Big difference. Thanks anyway for your valuable time.

The intent for these devices was to hold configuration info, and other field datta data. To go even more efprom See Section 6 for more information. Sign up using Facebook. There are two reasons I can think of for having a limit to the write pulse length: It was an ‘ad-hoc’ job, using pre-existing assemblies. Digest of Technical Papers.

AP AP, th x intel This situation was usually handled by either running the whole memory space for eepro, slowest device, or for the fastest memory, and then adding ‘wait-states’ for rata slower devices. Email Required, but never shown. The Group moderators are responsible for maintaining their community and can address these issues. EPROMs can’t be erased electrically and are programmed via hot carrier injection onto the floating gate. Most new ones withwrite cycles, before data transfers get iffy.
