Classification: CPC G | IPC G

Claim 16:
17. A first fire operation for an OTS selector, wherein the OTS selector is coupled to a transistor, and the first fire operation comprises:
setting a peak amplitude of a first fire voltage pulse and a peak amplitude of a gate voltage pulse; and
performing at least one cycle, comprising:
providing the first fire voltage pulse to the OTS selector and providing the gate voltage pulse to the transistor for turning on the transistor;
sensing an output current passing through the OTS selector in response to the first fire voltage pulse;
comparing a peak amplitude of the first fire voltage pulse with a maximum peak amplitude ensuring initialization of the OTS selector;
ending the first fire operation if the peak amplitude reaches the maximum peak amplitude;
comparing the output current with a target current indicative of initialization of the OTS selector if the peak amplitude is lower than the maximum peak amplitude;
ending the first fire operation if the output current reaches the target current; and
setting another first fire voltage pulse with a greater peak amplitude if the output current is lower than the target current.
