It has a 2Kbits of memory size arranged in 32 pages of 8 byte each. In Maysome important research eeeprom was disclosed by Fairchild and Siemens.

EEPROM – Wikipedia

The manufacturers usually specify the maximum number of rewrites being 1 million or more. Electronic Inventions and Discoveries: But what if the data came from some sensor or so? In the above setup, I knew feprom of course, datqsheet I myself wrote it.

It was also used on video game cartridges to save game progress and configurations, before the usage of external and internal flash memories. I corrected my code, recompiled, uploaded, tried Views Read Edit View history.

EPROMs can’t be erased electrically and are programmed datasyeet hot carrier injection onto the floating gate. Yes, I did read the datasheet, but it seems that I do not fully grasp some of the issues Next time you dataseet the I2C read routine, you give it an address, and again immediately say “have you got any data?

Magnetic tape Hard disk drive. 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. Flash memory is a type of EEPROM designed for high speed and high density, at the expense of large erase blocks typically bytes or larger and limited number of write cycles often 10, The theoretical basis of these devices is Avalanche hot-carrier injection.


This last bit is 1 for write and 0 for read operation. Paper data storage Drum memory Magnetic-core memory Plated wire memory Core rope memory s Thin-film memory Disk pack Twistor memory — Bubble memory — Floppy disk By using this site, you agree to the Terms of Use and Privacy Policy.

Products such as real-time clocksdigital potentiometersdigital temperature sensorsamong others, may have small amounts of EEPROM to store calibration information or other data that needs to be available in the event of power loss. You give the I2C device an address, and then immediately say “have you got any data”? Apparently, there should perhaps be some time between available and receive I had to ask it twice When data is to be read or write, first a start condition is created followed by device address, byte address and the data itself.

Many microcontrollers include both: 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.

One of their research includes MONOS metal – oxide – nitride -oxide- semiconductor technology, [6] which is used Renesas Electronics datawheet flash dataxheet integrated in single-chip microcontrollers until today. 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.


The manufacturers usually guarantee data retention of 10 years or more. In the industry, there is a convention to reserve the term EEPROM to byte-wise erasable memories compared to block-wise erasable flash memories.

Japanese inventions Non-volatile memory Computer memory. There is no clear boundary dividing the two, but the term “EEPROM” is generally used to describe dataxheet memory with small erase blocks as small as one byte and a long lifetime typically 1, cycles.

SPI Module of Arduino. Archived copy as title Wikipedia articles with GND identifiers.

Reading the datasheet gave me the wrong impression that I could get away with being impatient. But each FLOTOX structure is in conjunction with another read-control transistor because the floating gate itself is just programming and erasing one data bit. Choosing Motor For Robots. Archived PDF from the original on This data byte is to be written on or read by the microcontroller.

Finally a stop condition is provided. For more details on different operations and addressing, refer interfacing 24C02 with Erase is via an ultraviolet light source, although in practice many EPROMs are encapsulated in plastic that is opaque to UV light, making them “one-time programmable”.

United States Patent and Trademark Office. As is described in former section, old EEPROMs are based on Avalanche breakdown -based hot-carrier injection with high reverse breakdown voltage. Skip to main content.
