Abstract: An apparatus for correcting output impedance of a memory interface driving circuit, the apparatus comprising: a first PD driver including a plurality of first sub PD drivers connected to each other in parallel; a first control unit configured to sequentially change a first control code, the first control code being a combination of control signals for turning the plurality of first sub PD drivers on or off in each pull-down sweep; and a first comparator configured to generate a first output pattern, the first output pattern being a sequence of 0 or 1 representing a result of comparing an output voltage of the first PD driver generated according to the first control code with a first reference voltage, wherein the first control unit determines a first impedance correction code for the memory interface driving circuit from among the sequentially changing first control codes using the first output pattern.

Abstract: Provided is a virtual sensor system for a digital twin application. The virtual sensor system includes an edge gateway configured to collect data collected from physical sensors in the real world, apply the collected data to a virtual sensor model, and operate virtual sensors for configuring a digital twin world, and a virtual sensor framework configured to train the virtual sensor model using data, which is measured by the physical sensors, from the edge gateway and distribute the virtual sensor model to the edge gateway.
