For SCM (which 4DS is targeting) it is all about speed. Retention more important for Flash.
Good summary table on 4DS website http://www.4dsmemory.com/technology/reram
"The main reason that retention is far less critical than speed and endurance is the space close to DRAM is that DRAM is essentially a volatile memory. Its contents need to be read and written back (refreshed) every 60 milliseconds and any retention better than DRAM saves power. The reality is that a Storage Class Memory with a retention of just one day is an astonishing 1.5 million times (or 6 orders of magnitude) better than DRAM retention. A Storage Class Memory with a retention of 1 week, 1 month, or 1 year further boosts this to 10 million, 44 million, and half a billion respectively."
@hashtagyolo, I think that to accuse public company directors of "swindling" investors is a seriously defamatory allegation.
