METHOD FOR READ DATA AND APPARATUS THEREOF, AND COMPUTER READABLE MEDIUM

摘要

A data reading method, a data reading apparatus, and a computer readable medium are provided to maintain the same set up margin always by removing a skew between a data signal and a data strobe signal. A data transition detecting part(1010) includes a pulse signal generating part(1011). The pulse signal generating part detects a data transition of an external data signal, and generates a pulse signal. The pulse signal generating part includes a set up time operation part(1011-1) and an inverter. The set up time operation part determines a set up time. The set up time indicates a gap between data transition detection timing and data signal capture timing. The inverter inverts the pulse signal. A data capture flip-flop part(1020) captures a data signal by using the pulse signal as a trigger signal.
