What is the basic difference between a EEPROM and Flash Memory, dont say EEPROM needs a extra select transistor
Ok, I'm wondering why EEPROM is called ROM. I think it's because EEPROM depends on an electrical process to change the bits, rather than an electronic one. Can someone please confirm this and/or post the clarification? Mang 00:42, 4 March 2006 (UTC)
I added the following phrase in the leading section. Cafeduke ( talk) 07:49, 13 March 2018 (UTC) EEPROM typically allows a byte (or a word) to be erased, and re-written individually, while typical flash memory erase some region in the device at once.
I think this article could have separate chapters covering memory mapped (adress and data bus), serial EEPROM and history. I'm not into the old history parts myself, even though I've also been working on products with memory mapped EPROM's. -- Nordby73 00:26, 1 February 2006 (UTC)
In first line the def states (configuation) data.
True for PCs. But lots of EEPROM is in embedded systems where it stores entire programs, stored tables of data and logged data. It seems to me that the "configuration" part is a PC-centric view of EEPROMS. I'm guessing we each own several embedded systems for each PC we own and thus there would be more EEPROM used for programs and data then for configuration.
Thanks, John
EE = Electrically Erasable, EA = Electrically Alterable. EAROM/EAPROM devices were once marketed as superior to EEPROMs, since EEPROMs could only be erased completely, while EAROMs/EAPROMs offered a more granular control about which regions get erased. This is history, of course. Nowadays, the word EEPROM includes devices where individual bytes can be erased. -- Klaws 12:53, 5 June 2007 (UTC)
EAROM redirects to the EEPROM article, but EAROM is not mentioned at all! -- 92.74.244.179 ( talk) 17:24, 7 December 2008 (UTC)
I came here looking for for an understanding of EEPROM structuer and did not find it. I would have liked to see a paragraph describing how EEPROM works at the cell level. Perhaps something like, "An EEPROMS cell consists of 3 transistors configured as ..." along with a schematic of a cell and a generalized chip schematic. —Preceding

I also noticed EAROM redirects there with no mention to it. I just added an historical reference to EAROM in the solid-state drive article. If someone does not add some information I may take a shot at it shortly when I get a chance. § Music Sorter § ( talk) 04:09, 20 June 2011 (UTC)
Article says this: "However, an EEPROM chip has to be erased and reprogrammed in its entirety, not selectively."
I think this is misleading, if not incorrect. EPROMs had this limitation. The EEPROM limitation is that your read/write/erase operations *must* occur one byte at a time, rather than in larger blocks; making EEPROMS slower. Although modern EEPROMS allow page write operations. 75.84.184.44 ( talk) 01:44, 8 September 2010 (UTC)
Why is this tagged as an American Invention? According to the article, EEPROM was first studied, created, and patented in Japan, thus making it a Japanese invention. I'm going to change the tag to Japanese Inventions unless someone can prove it should in fact be tagged as an American invention. — Preceding unsigned comment added by HBBorges ( talk • contribs) 23:09, 6 May 2018 (UTC)
For example this part is comfusing: "One of their research studies includes MONOS (metal-oxide-nitride-oxide-semiconductor) technology, which used Renesas Electronics' flash memory integrated in single-chip microcontrollers", for what I see the first article on the matter is from 1983 but reading it I thought it came before the next studies listed.

There is an image an EPROM diagram. Are the geometries the same? Not sure if the image should be there. Starlighsky ( talk) 00:14, 21 October 2023 (UTC)
