Abstract: The present disclosure relates to methods of operating non-volatile memory devices. An example read operation method of a non-volatile memory device includes applying a first read voltage, generated from a voltage generator, to a selected wordline, performing a first sensing node develop operation associated with the first read voltage, and performing a first sensing operation associated with the first read voltage. While the first sensing node develop operation is performed, the voltage generator generates a second read voltage based on the selected wordline being disconnected from the voltage generator and thereby being floated.

Abstract: A transmitter device which transmits a first transmit signal and a second transmit signal having different wireless communication standards. The transmitter device includes a power amplifier that amplifies the first transmit signal in a first transmission mode. A first impedance circuit provides the amplified first transmit signal to a radio frequency output port. A second impedance circuit is connected to the first impedance circuit and provides an additional impedance to the first impedance circuit in the first transmission mode. A first switch provides the second transmit signal to the first impedance circuit in a second transmission mode. A second switch connects the second impedance circuit and a ground in the first transmission mode, and floats the second impedance circuit in the second transmission mode.
