Abstract

In this paper, the circuit is proposed that selectively changes the memory required to perform a write operation in a LUT composed of several spin-torque transfer magnetic RAM(STT-MRAM)s. When write a new data in the STT-MRAM LUT, unnecessary energy is consumed because the write operation is performed even though the data is the equal as the previous one. To overcome this problem, a comparison write scheme is proposed. The energy consumption is smaller than previous circuit's in [1], when 45 or less data is written again based on the 6bit-LUT having 64 memory cells.
