Abstract:
1. An electrical component having configurable characteristics that are non-volatile, comprising: a plurality of tunnel magneto-resistive (TMR) cells connected in series and arranged in groups of at least one first TMR cell and at least one second TMR cell, wherein each of the plurality of TMR cells are independently capable of being magnetized to have either a first resistance value or a second resistance value depending upon application of a configuration current pulse passing therethrough; a first end of the plurality of TMR cells is connected to a first voltage and a second end of the plurality of TMR cells is connected to a second voltage; a configuration conductor passes through the at least one first TMR cell in a first magnetization direction and the at least one second TMR cell in a second magnetization direction, wherein a voltage amplifier having an input and an output, the input is coupled to a series connection between the at least one first TMR cell and at least one second TMR cell, wherein the voltage amplifier output is at
