Nonvolatile Memory Cell Based on Memristor Emulator
Memristor, one of the fundamental circuit elements, has promising
applications in non-volatile memory and storage technology as it can
theoretically achieve infinite states. Information can be stored independently
in these states and retrieved whenever required. In this paper, we have
proposed a non volatile memory cell based on memristor emulator. The circuit is
able to perform read and write operations. In this memristor based memroy cell,
unipolar pulse is used for writing and bipolar pulse is used for reading.
Unlike other earlier designs, the circuit does not need external read/write
enable switches to switch between read and write operations; the switching is
achieved by the zero average bipolar read pulse given after the completion of
write cycle. In our proposed memristor based memory cell, single bit can be
read and any voltages from 0 to 5 volts can be written. Mathematical analysis
and the simulation results of memristor emulator based read write circuit have
been presented to confirm its operation
