Computer memory chips

This POTD is being posted 1 day late.  The reason for that is because my PC died.  Well to be strictly accurate a memory module failed which caused the blue screen of death and repeated reboots.  This in turn caused Windows to become corrupt which in turn meant I had to reainstall windows and all the applications I use.  Which in turn meant that I couldn’t process my POTD…. which in turn means it is being posted 1 day late.
