By first readout, the current input from a selected cell 13 is converted by a preamplifier 3 and a VCO 4 into pulses of a frequency inversely proportionate to the current value, and the number of the pulses within a preset time interval is counted by a counter 5 so as to be stored in a readout value register 6. A selected cell is then written to one of two storage states, and second readout is then carried out. The storage state of the selected cell is verified by comparing a count value of the counter for the second readout, a count value for the first readout as stored in a readout value register and a reference value stored in a reference value register 7 to one another. By the use of the VCO, the integrating capacitor for the current or reference pulse generating means, so far needed, may be eliminated to assure a small area, low power consumption and fast readout.

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.
