DFT-NEGF analysis of Fe/MgO/Fe MTJ having gate voltage over insulated barrier region (MgO) is presented. Because of different work functions of gate and barrier materials, transfer of density of states (DOS) in forbidden energy gap of MgO is found above Fermi energy due to Schottky effect. It is reported that diffused DOS allow high tunneling of majority channel current It shows high spin injection efficiency 0.9928, 0.9959 and 0.9871 with Tunnel Magneto Resistance (TMR) ratios 1743.30\%, 1450.06\% and 572.62\% at gate voltages 1V, 2V and 3V, respectively, left and right electrode voltage is 0.5V.
