Hi, I have this chip:
https://4donline.ihs.com/images/VipMasterIC/IC/TOSC/TOSCS25929/TOSCS25929-1.pdf?hkey=EF798316E3902B6ED9A73243A3159BB0
I want to dump its memory using programmer also i want to analyze it using oscilloscope/logic analyzer , what is the cycle speed Mhz/Sample rate of the devices in order them to work with this chip?
If it is possible, please explain how you calculated the result.
Thanks.

Look at page 5. This is a NAND flash, read and write cycles are internally timed and may vary in length depending on the age/wear on the blocks.

Which device can dump the contents of the NAND chip? and what its specifications should be?

Anything with enough I/Os... and is fast enough that you won't be annoyed waiting for it to finish reading. Even an Arduino will do it if you don't have anything else.
