  • Patent number: 11955173
    Abstract: First fire operations for an ovonic threshold switch (OTS) selector is provided. A first fire operation includes setting a peak amplitude of a voltage pulse, and performing at least one cycle, including: providing the voltage pulse to the OTS selector; sensing an output current passing through the OTS selector in response to the received voltage pulse; comparing a peak amplitude of the 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 voltage pulse with a greater peak amplitude if the output current is lower than the target current.
