Abstract

According to one embodiment, a variable change memory includes a bit line, a word line, a memory cell array, a resonance line, a clock generator, and a write driver. The bit line extends in a first direction. The word line extends in a second direction. The memory cell array includes blocks. The each block includes memory cells including a transistor and a variable resistive element. The resonance line connects to a bit line. The clock generator is arranged in the memory cell array and applies a voltage to the resonance line. The write driver supplies a write current to the bit line. The voltage oscillates at the predetermined period and the write current are supplied to the bit line.
