I see that in ALTERA device, Some device has M9K blocks and some have M10K blocks, but not both. Can I Know the reason?  

and why exactly M9K in Arria V, and why not M10K instead of M9K.

M10k are newer. Older technology has m9k.

Why 10 bits wide? 

I guess a lot of memory is used to generate 32bit wide blocks - so the extra bits are wasted. 

9 bits could be used for 8+parity. 

10 bits doesn't seem to help much with ECC. 

There must be a 'killer-ap' out there that needs it :-)

9 bits was always sold as 8 bits + parity. But Ive only ever used it for storage. 

Extra bits are always helpful for sideband status bits through a fifo.  

 

I just think more bits = more storage = more opportunity.
