60 switching cycles (a) under 1 mA set-CC (low set-CC) and (b) under 5 mA set-CC (high set-CC).
(c) Comparison of Ion and Ioff for the low and high set-CC. (measured at +0.3 V) (d) Correspondence between Vreset and Ion for the high set-CC. (e) Correspondence between Vset and Ioff for the high set-CC. (f) Correspondence of current level with respect to the sign of read voltage is examined.
