CIRCUIT FOR REDUCING NEGATIVE BIAS TEMPERATURE INSTABILITY

摘要

A control circuit comprises a first NOR gate, a first NMOS transistor, and a first PMOS transistor. The control circuit also comprises an output node. The control circuit further comprises a half latch keeper circuit coupled to a gate of the first NMOS transistor and to a gate of the first PMOS transistor. The half latch keeper circuit is configured to keep the output node at a logical 1 during a standby mode. The control circuit additionally comprises an operational PMOS transistor coupled to the output node. An output of the first NOR gate is coupled to a gate of the operational PMOS transistor. The control circuit is configured to turn off the operational PMOS transistor during the standby mode.
