Why does minecraft keep taking up ram?

I open minecraft and look at the usage of ram. It starts at 400 mb, then quickly jumps to 600-650. It keeps increasing until it has to close. It uses over two gigs of ram. I can't use my server for more than three minutes. This never happened before. I also have no mods, nothing that modifies the vanilla game or server other than a skin, but I've had that forever. I also have 8 gigs of ram, 4's usually available. It just keeps eating away at it.

Added (1). I'm using windows. I have 64 bit everything on a 64 bit system.

Update may have a memory leak so might have to wait for a bug fix. Also make sure if you have that much ram that your windows is 64 bit and that you have 64 bit java and that it's up to date since minecraft runs on java and 64 bit is better at memory management.

Look up the requirements for it. Minecraft shouldn't require ridiculous amounts of cpu or ram but still. Make sure your processor passes the requirements as well as your RAM. Also close any applications not being used while playing Minecraft. Let us know how things go
