Patent ID: 11955173
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A first fire operation for an ovonic threshold switch (OTS) selector, comprising:
setting a peak amplitude of a voltage pulse; and
performing at least one cycle, comprising:
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.
