Never heard that. If someone set up it , what will happen ? It must be amazing at least.
Because it is nonsense. RAM can by definition of RAM not calculate anything, but only store information.
There is almost no difference between calculating and storing/retrieving. A multiplication table can only store information, but it can also "calculate" products.
There is a big difference as in: the table itself (or the thing the information is storred on) can not calculate. You can calculate more efficiently while using such a table. That does not make the paper the table is written on a calculator.
