Thermal stability of magnetization in a nano-magnet is an important issue for the retention of stored data in a magnetic random access memory based on spin-torque switching. Within the thermal activation model, the distribution of the switching current of spintorque switching (I_c) at finite temperature is roughly proportional to the inverse of the thermal stability parameter (Δ). In this paper, we present a new method for evaluating Δ from the distribution of I_c. This method can give us correct Δ at any given pulse width.
