Hi is someone able to tell me what "WL" stands for? I know they are chips that are not STD commands, and usually read wit a .bb file, but my question is exactly what does "WL" stand for?
My guess is "Word Line" but this doesnt exactly fit the situation. Another would be Wear Levelling, but this is even less likely.

Its been bugging me for years! Wink

I don't know, WordLine maybe??

WL NAND has subpages.. ie: TLC NAND..

WL Mode

Page 123 - Lower - Prefix 01h
Page 123 - Middle - Prefix 02h
Page 123 - Upper - Prefix 03h


SLC Mode

Page 123 - Prefix A2h


SLC Mode is pretty cool, you lose 2/3rds capacity but gain reliability and speed by merging the subpages into one.

seems to be WordLine.
