A system is provided for transmitting signals. The system comprises a first processing unit, a memory subsystem, and a package. The first processing unit is configured to include a first ground-referenced single-ended signaling (GRS) interface circuit. The memory subsystem is configured to include a second GRS interface circuit. The package is configured to include one or more electrical traces that couple the first GRS interface to the second GRS interface, where the first GRS interface circuit and the second GRS interface circuit are each configured to transmit a pulse along one trace of the one or more electrical traces by discharging a capacitor between the one trace and a ground network.
