Semiconductor system with training function for a data strobe signal

摘要

A semiconductor system includes a controller and a semiconductor device. The controller generates a clock signal and updates external count signals in response to an external update signal. The semiconductor device generates count signals by counting pulses of a strobe signal during a period when a section signal is in an active state. The section signal is generated in response to a first control signal including pulses that are periodically generated. The semiconductor device also generates the external update signal and the external count signals if a combination of the count signals is changed.
