==Is "Flash ROM" NVRAM?==
== Renaming from Computer memory to Electronic memory ==
Is [[Flash ROM]], i.e. Flash memory, categorized to [[NVRAM]]? I think it is a kind of ''ROM'', as it is named. In addition, current [[Solid-state drive|SSD (Solid State Drives)]] use [[NAND gate]] type Flash ''ROM'', associated with a controller and some buffer RAMs. It is also not a NVRAM but a ROM, to pretend as if it is a RAM with controller.

I asked the user who changed the article name to comment on the justification or point to the thread supporting the name change [[User_talk:Mange01#Renaming_Computer_memory_to_Electronic_memory|here]]. [[user:Music Sorter|'''<span style="font-family:veranda,sans-serif;background:lightblue;color:Blue">&sect;&nbsp;Music&nbsp;Sorter&nbsp;&sect;</span>''']] ([[User talk:Music Sorter#top|talk]]) 08:36, 13 July 2011 (UTC)
:Sorry for my ambivalence. I changed my mind and moved it back to Computer memory. Instead [[electronic memory]] now points at [[semiconductor memory]], which is a more well-defined term. I have now rewritten the lead of this article, which did include some guessing and incorrect statements. [[User:Mange01|Mange01]] ([[User talk:Mange01|talk]]) 11:58, 13 July 2011 (UTC)

==Merge with Computer data storage==
The two articles are currently covering essentialy the same topic, with "computer memory" being the more common name. See section [[Computer data storage#Characteristics of storage|Characteristics of storage]] at Computer data storage, its contents are parallel to those in [[computer memory]]. It's arguable that [[Computer data storage]] should refer to persistent storage as in a [[Data storage device]], but it's not dedicated to that topic right now; so I think a merger makes sense.

:Yes, according to the lead there, [[Flash memory]] is a type of [[non-volatile memory]]. Flash can also be used as ROM if it is programmed at the factory and no write line connected or otherwise write protected. ~[[User:Kvng|Kvng]] ([[User talk:Kvng|talk]]) 17:47, 23 May 2024 (UTC)
::It's not at all clear to me that such a distinction exists. There is a great deal of overlap in the content of both articles, and indeed, the first line of the [[Computer data storage]] article says that the term is synonymous with "computer memory"! If computer memory is in fact a subset of computer data storage, than with the amount of overlap today, I'd say the best option is to make "Computer memory" a redirect to the appropriate subsection of "Computer data storage".--[[User:Xiaphias|Xiaphias]] ([[User talk:Xiaphias|talk]]) 18:02, 18 November 2014 (UTC)
:::It is clear to me that a distinction exists; off the top of my head something like Computer Memory refers to that information directly accessible by the computer instruction set whereas Computer Storage or Computer Data Storage refer to that information indirectly accessible by the computer thru other means such as an input/output channel. I can probably find reliable sources with better definitions than the ones I postulated above. If the articles do not make the distinction clear we should fix them.

::::I don't think so actually. At a cursory glance, it would seem that memory vs storage are just (somewhat?) arbitrary distinctions, and in which case, I support the merge. This discussion has actually [[Talk:Computer data storage#Cleanup and merging|already happened]], 9 years ago, minus a day here and there, too. There's more of those discussions scattered about at different dates on that talk page too. A notable quote from that talk page: <blockquote>''The Multics operating system really blurred the separation. In it everything had a "memory address", regardless of where it physically resided (disk, tape, punched card, printer, etc.). There were no system calls for I/O, except to map and unmap files and devices to their addresses. Once mapped the file or device was accessed just like any other memory as far as the programmer was concerned. -- 205.175.225.5 00:15, 23 September 2005 (UTC)''</blockquote> - [[User:BlueFenixReborn|BlueFenixReborn]] ([[User talk:BlueFenixReborn|talk]]) 01:47, 11 December 2014 (UTC)

Is "Flash ROM" NVRAM?

[edit]

Is Flash ROM, i.e. Flash memory, categorized to NVRAM? I think it is a kind of ROM, as it is named. In addition, current SSD (Solid State Drives) use NAND gate type Flash ROM, associated with a controller and some buffer RAMs. It is also not a NVRAM but a ROM, to pretend as if it is a RAM with controller.

On the contrary, EEPROM sometimes consists of 6-transistors per bit RAM structure (Random-access memory#Memory cell) with non-volatile memory cell. NVRAM article describes EEPROM as a kind of NVRAM. But EEPROM can be made with 2 transistors per bit at the minimum. Cafeduke (talk) 12:56, 18 March 2018 (UTC)[reply]

Yes, according to the lead there, Flash memory is a type of non-volatile memory. Flash can also be used as ROM if it is programmed at the factory and no write line connected or otherwise write protected. ~Kvng (talk) 17:47, 23 May 2024 (UTC)[reply]
