Ram is relatively cheap, the scaling continually shows a downward trend in price per GB.
Prices today are roughly where they were five years ago, see here. They are more than double that of a year ago. Historically the memory market has been a boom/bust market, with every bust we saw consolidation. Last time (2012/13) Micron absorbed Elpida. We're now down to three major memory vendors: Samsung, SK Hynix and Micron. Fewer vendors means less competition. At the same time we see a slow down in Moore's law. I don't think another collapse in memory prices is just around the corner.
