SIGNAL TRANSMISSION SYSTEM BETWEEN COMPONENTS SUCH AS MEMORIES

摘要

PROBLEM TO BE SOLVED: To provide a high-speed low amplitude bus by preventing repetitive reflections in a branch wiring. SOLUTION: A signal transmission circuit comprising one unit or more each having a sending circuit and a transmission line to deliver a signal generated by the transmission circuit; one unit or more each having a receiving circuit and a transmission line to receive the signal received by the receiving circuit and; a transmission line for transmission among the units is connected to power supplies at one or more position of the inter-unit transmission line via a resistor, and an element with a resistance nearly equal to a value resulting from subtracting a half of the effective impedance of the inter-unit transmission line from the impedance of the in-unit transmission line is placed between the in-unit transmission lines having the sending circuit and the inter-unit transmission line.
