I suggest merging [[single-level cell]] into [[multi-level cell]].
Currently *both* articles talk about *both* MLC and SLC.
Rather than describe the differences between them in 2 places, I think it makes more sense to describe the differences between them in one place.

Wholeheartedly agreed. Having separate entries for SLC and MLC is like having separate entries for head and tail of a coin. —Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/85.179.32.131|85.179.32.131]] ([[User talk:85.179.32.131|talk]]) 00:10, 28 November 2008 (UTC) 

==MLC NOR==

This article only mentions MLC NAND, but MLC NOR is also available. --[[Special:Contributions/192.54.193.53|192.54.193.53]] ([[User talk:192.54.193.53|talk]]) 13:43, 19 February 2009 (UTC)

== CRC algorithm ==

"requires an algorithm that can correct errors up to five bits".. five bits per what? Byte?

== Neutrality ==

Anybody else feel like the meat of this article feels like a Samsung advertisement? Particularly the line "Samsung has pioneered high-performance". — Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Antiduh|Antiduh]] ([[User talk:Antiduh|talk]] • [[Special:Contributions/Antiduh|contribs]]) 17:50, 22 March 2014 (UTC) 

== MLC wears out quicker than single level cell ==

lots of places talk about how MLC has more [[flash memory#Memory wear]] and so will stop working after several times fewer read-erase cycles. The numbers thrown around seem different everywhere though. [[Special:Contributions/76.119.30.87|76.119.30.87]] ([[User talk:76.119.30.87|talk]]) 01:37, 26 November 2014 (UTC)

== Intel 8087 ==
What are the relations of an Intel x87 FPU-Coprocessor with Multi cell flash? And why should it use 2 bits per cell??? It's just an extended processing unit, when Intel run out of space on their x86 dies, so they added a second chip to do the complicated floating point math. Nothing to do with flash memory.

:The two-bits-per-cell technology was used for the 8087's microcode ROM. I clarified the sentence. — Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/2003:C8:B71B:900:F9E5:A909:C868:14CB|2003:C8:B71B:900:F9E5:A909:C868:14CB]] ([[User talk:2003:C8:B71B:900:F9E5:A909:C868:14CB#top|talk]]) 21:28, 23 January 2023 (UTC) 

== Explanation please ==

I don't understand why TLC is called TLC.
*SLC stores 1 bit so it has 1 level:
Below that level means 0 and above means 1.

*2 Bit MLC stores 2 bit so it has 3 levels:
Below level 1 means 00
above level 1 and below level 2 means 01
above level 2 and below level 3 means 10
above level 3 means 11

*TLC stores 3 bit so it has 7 levels:
Below level 1 means 000
above level 1 and below level 2 means 001
above level 2 and below level 3 means 010
above level 3 and below level 4 means 011
above level 4 and below level 5 means 100
above level 5 and below level 6 means 101
above level 6 and below level 7 means 110
above level 7 means 111

Notice that you have listed four states (which gives you two bits) and eight states (which gives you three bits in the examples above. This is a common problem for non-computer people because 0 can be used for counting. A mathematician would probably say it has to do with ordinal versus cardinal numbers. For TLC you say there are seven
'levels' which might be more appropriate to call thresholds. If you draw a line an split it into 8 equal parts you will see there are seven dividing lines. Those lines would correspond, very roughly, to the charge level on the cell.[[User:Ee79|Ee79]] ([[User talk:Ee79|talk]]) 20:47, 5 November 2018 (UTC)

'''Shouldn't it be called 7 level cell?''' [[User:ForeverAlone174|ForeverAlone174]] ([[User talk:ForeverAlone174|talk]]) 09:32, 20 November 2015 (UTC)
: I don't get that naming choice either. 
:If it means "bit", why was it not just named "bit" ? 
:What if a cell can discriminate 2 thresholds = 3 values = 1.5 bits ? [[User:Musaran|Musaran]] ([[User talk:Musaran|talk]]) 11:28, 31 January 2018 (UTC)

::Names don't have to follow logic perfectly and they are often Marketing influenced. Besides, it has a benefit this way in that you will run out of single digit integers fast and have to make larger acronyms [[User:Fs|fs]] 09:19, 30 November 2018 (UTC)

== QLC ==

No one talking about QLC cells? Quad-Level Cells?

== There's no such thing as a Multi-Level Cell ==

This article is about something that doesn't exist, i.e. a memory cell (described here as a single FG MOSFET) which is 'capable of storing more than a single bit of information'. A single FG MOSFET can only store a single charge of electrons, and thus a single bit of information. It's how this charge is interpreted that provides the multi-level capability, and that interpretation is done by other components within NAND flash. You can have SLC, MLC and TLC NAND flash, but not a MLC or TLC FG MOFSET cell.

The article veers between cell, NAND flash, memory and other descriptors, but the title is cell. Most, if not all, of it should be in the NAND flash article. [[User:Kletzmer|Kletzmer]] ([[User talk:Kletzmer|talk]]) 19:07, 7 November 2020 (UTC)

== Merge StrataFlash into this page ==

[[StrataFlash]] appears to be an old Intel brand name for MLC NOR flash. As such, the content could be merged into this article, perhaps even reduced to a couple sentences, as they appear to be no longer using the name. [[User:Irene Twoth|Irene Twoth]] ([[User talk:Irene Twoth|talk]]) 23:15, 6 February 2026 (UTC)

:{{u|Irene Twoth}}, this has gone unopposed and you should be good to merge them if this is something you're still interested in. '''[[User:Thebiguglyalien|Thebiguglyalien]]''' ([[User talk:Thebiguglyalien|talk]]) 00:48, 17 March 2026 (UTC)
