Abstract:
A toggle magnetic random access memory includes a first memory array, a second memory array and a controller. The first memory array includes a plurality of first memory cells including magnetoresistive elements. The second memory array includes a plurality of second memory cells including magnetoresistive elements and differs from the first memory array in write wirings used for writing. The controller controls the first memory array and the second memory array such that a first state in which a first burst write operation in the first memory array is executed and a second state in which a second burst write operation in the second memory array is executed are alternately executed in a continuous burst write mode. Accordingly, the continuous burst write operation can be executed at the high speed without any drop in the reliability and any increase in the circuit area.
