there was a ready-boost file equivalent to the size of pendrive with no delete option. I have aomei Disk management .
I tried to format with it no luck again. then i deleted the partition and after there i cant see my pendrive in my computer where all the drives are located.But my pendrive is getting detected .

Nothing happened. I cannot see my pen drive being listed in This PC.
But it getting detected in Disk management. With no options except help and properties listed.

If a drive or partition does not have a drive letter assigned to it, it will not show up in My Computer or explorer. Did you try diskpart?

Sounds like the drive has failed. I've used readyboost in the past with Windows 7 and no problems repurposing the thumb drive after.

Just because it worked yesterday doesn't mean it will work again today? I don't have any other suggestions, you've already done everything I would have tried if it was mine. Looking at your diskpart screen shot again, it looks like you cleared the read only and then set it back to read only? Why did you do that? Just run attributes disk clear readonly.

IMHO it's broken/defective, replace it.

I've had one that looks fine, shows full 8 gig capacity available but has a bad cell on it somewhere. Once you write past about 3 gigs worth of files it errors. It even formatted without errors. Clunk.

You can partition it around bad part but for small drives it just doesn't pay to do it.

Even then, to me, that drive was not to be trusted, so I ditched it. I ran a few utilities at the time to confirm it was bad and chucked it. Flash drives are pretty cheap these days.
