  The present manuscript deals with the realization of Processing In-memory
(PIM) computing architecture using Quantum Dot Cellular Automata (QCA) and
Akers array. The PIM computing architecture becomes popular due to its
effective framework for storage and computation of data in a single unit. Here,
we illustrate two input NAND and NOR gate with the help of QCA based Akers
Array as a case study. The QCA flip-flop is used as a primitive cell to design
PIM architecture. The results suggested that both the gate have minimum power
dissipation. The polarization results of proposed architecture suggested that
the signals are in good control. The foot print of the primitive cell equals to
0.04 micron^2, which is smaller than conventional CMOS primitive cell. The
combination of QCA and Akers array provides many additional benefits over the
conventional architecture like reduction in the power consumption and feature
size, furthermore, it also improves the computational speed.
