A semiconductor system includes a first semiconductor device configured to output a clock and pattern data, configured to receive a strobe signal and output data, and configured to adjust a duty ratio of the strobe signal by comparing odd data and even data that are generated from the output data and the pattern data, in synchronization with the strobe signal and a second semiconductor device configured to store the pattern data in synchronization with the clock, configured to output the clock as the strobe signal by adjusting a duty ratio of the clock, and configured to output the stored pattern data as the output data.

Semiconductor system for performing a duty ratio adjustment operation

A data storage apparatus is provided to include a memory device including memory cells for storing data; and an interface circuit coupled as an interface between the host device and the memory device and configured to transmit a transmission signal to the host. The interface circuit includes a delay circuit configured to generate a delay code and is configured to generate an additional signal to be combined with the transmission signal based on the delay code.

Data storage apparatus and interface circuit therefor

A memory controller includes a plurality of control signal pads and selectively controls a first-type memory and a second-type memory. The memory controller also includes a control signal generation unit configured to generate a control signal for controlling a selected memory. The memory controller further includes a control signal transfer unit configured to apply bits of a first control signal generated for controlling the first-type memory to respective control signal pads of the plurality of control signal pads, apply bits of a second control signal generated for controlling the second-type memory to a first control signal pad group selected among the plurality of control signal pads, and apply the second control signal to a second control signal pad group which is selected among the plurality of control signal pads independently of the first control signal pad group.

Memory controller, data storage device, and storage system having the same

An optical transceiver includes an optical transmitter and an optical receiver. The optical transmitter includes a laser diode configured to convert a current signal into an optical signal; a main driver comprising first and second output terminals that have a differential structure, the main driver configured to drive the first and second output terminals in response to differential input signals and to provide the current signal to the laser diode through the first output terminal; and an impedance balancer configured to match impedances of the first and second output terminals by adjusting the impedance of the second output terminal according to signal states of the first and second output terminals.
