Abstract
Embodiments of the invention are generally directed to systems, methods, and apparatuses for time-multiplexed dynamic on-die termination. In an embodiment, an integrated circuit receives, during a first clock, an on-die termination (ODT) activation signal at its ODT pin. The integrated circuit also receives, during a second clock, an ODT value selection signal on its ODT pin. In an embodiment, the integrated circuit prevents a reset of the state of the ODT activation signal for a predetermined period of time to enable the multiplexing of signals on the ODT pin. Other embodiments are described and claimed.
