  Construction of parallel logic gates at nano-scale level undoubtedly improves
the efficiency of computable operations. In this work we put forward a new idea
of designing two distinct logical operations {\em simultaneously} in the two
output leads of a three-terminal bridge setup which on one hand is highly
stable as all the results are valid for a wide range of parameter values and on
the other hand easy to engineer. Our system can be reprogrammed to have all the
two-input logic gates with two operations at a time by selectively choosing the
physical parameters describing the system, viz, Rashba spin-orbit (SO)
interaction, magnetic flux, and Fermi energy. Finally, we explore the possible
storage mechanism as well using our model.
