It was also used on video game cartridges to save game progress and configurations, before the usage eeeprom external and internal flash memories.

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. 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.

The intent for these devices was to hold configuration info, and other field alterable data.

During storage, the electrons injected into the floating gate may drift through the insulator, especially at increased temperature, and cause charge loss, reverting the cell into erased state. However, if you are looking to program EEPROMs, you may get good ideas from the Willem programmer, as it seems to be open-source eerom some variety. If that were the intended purpose, however, I would expect a specification that would indicate 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.

Subject of the new topic: If the device rejects any write cycles that are datz long, that may help guard against erroneous write operations in cases where a system operation gets disrupted e. SLEU eeprom programmer circuit diagram Text: Intel is com m itted to the technology of.


The theoretical basis of these devices is Avalanche hot-carrier injection. EEPROM still requires 2 transistors structure per bit to erase a dedicated byte in the memory, while flash memory has 1 transistor per bit to erase a region of the memory.

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.

When I set up my shop a few years ago when I started grad school, I got a programmer from Conitec.


Japanese inventions Non-volatile memory Computer memory. Inone of electrically re-programmable non-volatile memory was invented by Fujio Masuoka at Toshiba, who is also known as the inventor of flash memory.

Theoretical basis of the physical phenomenon itself is the same as today’s flash memory. Home Questions Tags Users Unanswered.

It was the 70’s think polyester leisure suits. Digest of Technical Papers. I am still just learning about electronics on my own, so please bear with me.

Thewith its very fast. If the part uses dynamic latches to hold the address, those latches may only be able to hold their value for a certain length of time. EPROMs can’t be erased electrically and are programmed via hot carrier injection onto the floating gate. So if the write pulse is too long, you clear the chip.

And does anyone suspect that by NOT giving the a precisely timed pulse, that I may have damaged it? A byte o f m emcom prehensive discus sion o f the operation o f the board w ith the
