MAGNETIC RANDOM ACCESS MEMORY AND READ CIRCUIT THEREOF

A magnetic random access memory and a read circuit thereof. The read circuit comprises a sense amplifier, a reference array, and a read array. The reference array comprises a first reference resistor, a second reference resistor, a first storage unit, a second storage unit, a first controllable switch, a second controllable switch, and a switch transistor; a first end of the first reference resistor and a first end of the second reference resistor are separately connected to the switch transistor; a first end of the first storage unit is separately connected to a second end of the first reference resistor and a second end of the second reference resistor; a first end of the second storage unit is separately connected to the second end of the first reference resistor and the second end of the second reference resistor; the second end of the first storage unit is connected to a second end of the first controllable switch; the second end of the second storage unit is connected to a second end of the second contr
