Chat Sessions - Memory engine a good fit?

I have an online chat service that stores chat sessions in an InnoDB table. Each user in a chat room makes a request to the server every few seconds. The script requested needs to query the user sessions table with a SELECT statement for all the users currently in the room. But, it also needs to UPDATE the user sessions table to store information like a timestamp of the last request and the key of the last served message.

It seems like the Memory engine would be a good fit considering this data is small and expendable when there's a crash... But, I'm not sure about the high volume of UPDATE queries. Would this be okay with Memory engine's table locking or should I stay with InnoDB and its row locking?
