Patent ID: 8625338

Claim:
A magnetic bit cell write circuit comprising: a first write driver applying a first voltage above a fixed potential to a first terminal; a second write driver applying a second voltage that is higher above the fixed potential than said first voltage to a second terminal, the second write driver including a level shifter configured to shift between the first voltage and the second voltage; and at least one magnetic tunnel junction (MTJ) structure coupled at the first terminal at a first side to said first write driver and coupled at the second terminal at a second side to said second write driver, wherein the first side of said MTJ structure receives said first voltage and the second side of said MTJ structure receives a ground voltage to change from a first state to a second state and the second side of said MTJ structure receives said second voltage and the first side of said MTJ structure receives said ground voltage to change from said second state to said first state, wherein said first voltage is based at least in part on a core network voltage and said second voltage is based at least in part on an input/output (I/O) network voltage.
