  Developing the field of neuromorphic quantum computing necessitates designing
scalable quantum memory devices. Here, we propose a superconducting quantum
memory device in the microwave regime, termed as a microwave quantum
memcapacitor. It comprises two linked resonators, the primary one is coupled to
a Superconducting Quantum Interference Device, which allows for the modulation
of the resonator properties through external magnetic flux. The auxiliary
resonator, operated through weak measurements, provides feedback to the primary
resonator, ensuring stable memory behaviour. This device operates with a
classical input in one cavity while reading the response in the other, serving
as a fundamental building block toward arrays of microwave quantum
memcapacitors. We observe that a bipartite setup can retain its memory
behaviour and gains entanglement and quantum correlations. Our findings pave
the way for the experimental implementation of memcapacitive superconducting
quantum devices and memory device arrays for neuromorphic quantum computing.
