SIGNAL TRANSMITTING APPARATUS AND SIGNAL TRANSMITTING METHOD

摘要

A signal transmitting apparatus includes: a plurality of data transmission lines that transmit output data to a memory; a plurality of delay units that are correspondingly connected to the plurality of data transmission lines, that delay test data according to a delay signal for a prede¬ termined time, and that output the delayed test data to each of the data transmission lines; and a transmitting/receiving controller that compares the stored data in the memory with the test data to adjust the delay signal, and that outputs the adjusted delay signal to each of the plurality of delay units. With this configuration, when data is transmitted to a memory through a data bus, a delay value can be adjusted among a plurality of signal lines constituting a data bus, and thus signal transmission can be performed uniformly.
