Looking for in-memory database that can write to disk as well

I'm looking for vendors who sell a specialized kind of database. I need the database to be implemented in memory, but with the ability to flush changes in the database to disk as a background operation. This will be used to store temporary data that needs to be accessed from multiple machines, but which by its nature does not require saving to disk *as part of the transaction* that creates the data.

Ideally, the database would allow a transaction from a remote client, write the information to memory, then notify the client that the transaction is finished. Later, as time allows, the database would flush the transaction to disk for permanent storage, so it would be available the next time it starts up.

Of course we could implement this ourselves, using a write cache layer on top of a commercial database, but I'm hoping someone already has this done as a product, or maybe there is an option in some commercial databases for a table attribute that means something similar to "write-back transaction".

Any pointers or tips are appreciated.
