EEPROM, slightly O.T.

First hit on google: D to be more accurate: The new topic will begin with this message. Your email is included with the abuse report. Japanese inventions Non-volatile memory Computer memory.

An example that I have worked with is this one cva. What’s the deal with the ? Siemens Forschungs und Entwicklungsberichte.

Home Questions Tags Users Unanswered. This situation was usually handled by either running the whole memory space for the slowest device, or for the fastest memory, and then adding ‘wait-states’ for the slower devices.

At 10mS per byte, it would get quite tiresome.

In either case, ns seems like a curiously short maximum. Back when I just got started in the electronics business, I was working as tech and general slave. EEPROM also E 2 PROM stands for Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers, integrated in microcontrollers for smart cards and remote keyless systemand other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed.

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.

System upgrades to 5 volt only operation can be im plem ented, seprom, by removing the 21V and w rite shaping circu itry. The 1us maximum write pulse time seems really weird, since many processors would need extra circuitry in order to meet that spec. If you write to the same address at one write per 10mS, you’d kill that byte in about 20 minutes. This meant they could not work down to DC.

I’ve never used the Willem Programmer, I don’t sell it, etc. In early s, some studies, inventionsand development for electrically re-programmable non-volatile memories were performed by various companies and organizations. The address needs to be held for an entire write cycle, so any dynamic latches would need to be able to deal with that. Magnetic tape Hard disk drive.

If that were the intended purpose, however, I would expect a specification that would fata that write pulses within a certain range are guaranteed to be accepted, write pulses that are outside a larger range would be guaranteed to be ignored, and those between the two ranges might arbitrarily be accepted or ignored.

Some as low a 10, For example here is the datasheet for the 26C64 write timing: 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.

Egg on my face. Hello, Forgive this slightly off-topic question: This cannot be undone. The can be easily eepron and reprogrammed on a byte basis. The Write pulse time is a minimum specification and typically has no upper bound. When I set up my shop a few years ago when I started grad school, I got a programmer from Conitec. The diode path speeds recovery of the 0.

Search Only Within This Topic. Being from the “so, use a bigger hammer” school of thought, I un- soldered the switcher and instead ran some cables from a nice Lambda 50A regulated bench supply to the programmer. This page was last edited on 20 Octoberat Dual dat detection lo gic allow s the A to use an existing, externally supplied high voltage programming pulse required w ith the toexisting socket.

Email Required, but never shown. It is seen that the threshold.

28C16 Datasheet(PDF) – STMicroelectronics

Most NOR flash memory is a hybrid style—programming is through hot carrier injection and erase is through Fowler—Nordheim tunneling. It used an 8-pin TI switching chip to generate the programming voltages. Sgeet me of the Old Apple ][ Disk ][ Drives. Managing Global Technology in shset 21st century. One day A good customer came in the shop all upset that his drive was dead, I hald it to my nose and went to the back to get a screwdriver and a chip.

It was an ‘ad-hoc’ job, using pre-existing assemblies. From Wikipedia, the free encyclopedia. Thanks anyway for your valuable time. When the Erase.

After sufficient number of rewrite cycles, the difference becomes too small to be recognizable, the cell is stuck in programmed state, and endurance failure occurs.
