In-memory Database

I'm new to Oracle.
I have a relatively small database (~100MB) and 1GB of memory on the server. What I want to to to speed up little bit is to put the database into memory. So all reads will be from memory and all writes - to the disk with memeory also updated.
How can I do this? How to place whole database into the memory.
