Abstract

STT-MRAM excels with fast reads, low write power, and high endurance, making it a key focus in emerging non-volatile memory research. However, write randomness, different P and AP write times, and temperature fluctuations challenge write efficiency and reliability. Fixed write cycle designs ensure state switching but waste power. This paper examines optimized write self-termination, write driver, word line driver, and peripheral auxiliary circuits for write. Write self-termination circuits save energy by detecting MTJ resistance changes to stop the write operation early. They each have advantages in terms of area, sensing margin, and speed, but they cannot balance all of them. In addition, in high-density and high-capacity storage, the parasitic capacitance effect and IR drop will reduce the drive ability of the write driver circuit. So this article also studies the write drive circuit, word line drive circuit, and peripheral auxiliary circuit to improve the write drive ability.
