Abstract:
A dynamic random access memory (DRAM) device includes an on-die termination (ODT) controller including an input to receive an ODT signal from a memory controller, and ODT circuitry to terminate an interface circuit, the interface circuit to provide a data signal between the memory controller and the DRAM device. The ODT controller is configured in a first impedance switching mode to terminate the interface circuit at a first impedance level in response to a first state of the ODT signal, to terminate the interface circuit at a second impedance level in response to a second state of the ODT signal, and to terminate the interface circuit at a third impedance level in response to a change in the ODT signal from the first state to the second state, the third impedance level being between the first impedance level and the second impedance level.
