Abstract: A serial communication method for a layered communication architecture includes a first layer, a second layer that is higher than the first layer, and a third layer that is higher than the second layer. The serial communication method includes transferring a first signal to the second layer based on a signal received through a communication line, the transferring performed by the first layer. The serial communication method further includes informing the third layer of reception of the first signal, the informing performed by the second layer; responding to the second layer based on whether there is a task to be performed, the responding performed by the third layer; transferring a second signal to the first layer based on a response from the third layer the transferring performed by the second layer; and entering a power saving state according to the second signal, the entering performed by the first layer.

Abstract: A transmitter includes: a pulse amplitude modulation encoder that encodes serial data to multi-bit transmission data of a first data group and a second data group; a first driver that converts first multi-bit transmission data of the first data group to a first differential signal having a first voltage swing width; a second driver that converts second multi-bit transmission data of the second data group to a second differential signal having a second voltage swing width narrower than the first voltage swing width; a first voltage regulator that provides to the second driver a first low swing voltage for generating the second differential signal; a second voltage regulator that provides to the second driver a second low swing voltage less than the first low swing voltage; and a constant current load switch that provides a current path between the first and second voltage regulators depending on deactivation of the second driver.

Abstract: A semiconductor circuit including a clocked comparator and an offset application circuit. The clocked comparator is configured to receive a first input signal and a second input signal from a host and compare the first input signal and the second input signal. The offset application circuit is configured to apply an offset to the first input signal. The clocked comparator is configured to be driven based on a reference clock provided from the host.
