Future memory technologies: -- bayko@borealis.cs.uregina.ca, in comp.arch

• DVRAM (Deja-Vue RAM) - the CPU thinks it has the data before it actually does.
• HRAM (Hearsay RAM) - CPU talks to other CPUs and uses what they all think the data is, instead of accessing the actual data (which may be different).
• 711RAM (Seven-Eleven RAM) - always available, but may be held up during the night shift.
• ARAM (Audio RAM) - like video RAM, but describes the image verbally instead.
