Abstract
The present disclosures concerns a register cell comprising a differential amplifying portion containing a first inverter coupled to a second inverter such as to form an unbalanced flip-flop circuit; a first and second bit line connected to one end of the first and second inverter, respectively; and a first and second source line connected to the other end of the first and second inverter, respectively; characterized by the register cell further comprising a first and second magnetic tunnel junction electrically connected to the other end of the first and second inverter, respectively. The shift register disclosed herein can be made smaller than conventional shift registers and power consumption during the write and read operation of the shift registers can be low. The shift register disclosed herein can be made smaller than conventional shift registers and power consumption during the write and read operation of the shift registers can be low.
