Last year, PC demand slackened and memory manufacturers had a glut of supply. As usual for this situation, the various manufacturers slashed prices in order to grab market share and put each other out-of-business. For a while late last year, memory was selling retail for less than half of what it costs to manufacture. In late Nov., Hynix became the first to throw up the white flag and they ceased memory production. Samsung and Micron agreed to cut production, the supply glut ended, and memory prices are now in line with the cost of production.
The only uncertainty right now is the fate of Hynix. If Micron buys them out, as they probably will, then Micron will become the largest mem producer in the world, with a firm control on supply, and prices will probably go up again. If Micron does not end up buying Hynix, which is possible because Hynix's many creditors are concerned about their already high losses, then the competition could begin anew.
It's extremely unlikely that we will see prices like last fall again, regardless of what happens.
