NvIOpRAM chip or module has only a few pinouts (Power, Ground and Read/Write enable) and optical input/output for the laser beam.  (Unfortunately, regular electronic semiconductor technologies do not allow to greatly decrease the size of chip and at the same time increase the density of information, since it is correlated to the problem of placing pinouts on a chip.  A large amount of pinouts limits the speed).  This memory does not have any moving mechanical parts. Complete lack of mechanical parts combined with ultra-high density, ultra-high speed and extremely compact size distinguish this memory from all existing memories.
