Abstract: A memory is provided in which a scan chain covers the redundancy logic for column redundancy as well as the redundancy multiplexers in each column. The redundancy logic includes a plurality of redundancy logic circuits arranged in series. Each redundancy logic circuit corresponds to a respective column in the memory. Each column is configured to route a shift-in signal through its redundancy multiplexers during a scan mode of operation.

Abstract: The RC sensor circuit includes a driver circuit that includes an output configured to drive the RC sensor circuit to a drive voltage using a representative copy of a current that drives an electronic circuit line. The RC sensor circuit includes an integration capacitor. The integration capacitor is configured to integrate the representative copy of the current over a first time period to generate a first representative voltage and over a second time period to generate a second representative voltage. The RC sensor circuit includes a sampling circuit coupled to the integration capacitor. The sampling circuit is configured to determine a first sample voltage by sampling the first representative voltage and a second sample voltage by sampling the second representative voltage. A ratio of the first sample voltage and the second sample voltage is indicative of an RC time constant of the electronic circuit line.

Abstract: A resistor-capacitor (RC) sensor circuit of an electronic device is driven to a drive voltage using a representative copy of a current that drives an electronic circuit line of the electronic device. The RC sensor circuit is to sample voltages that are indicative of an RC time constant of the electronic circuit line. A first sample voltage is determined by sampling a first representative voltage generated at the RC sensor circuit by driving the RC sensor circuit with the representative copy of the current over a first time period. A second sample voltage is determined by sampling a second representative voltage generated at the RC sensor circuit by driving the RC sensor circuit with the representative copy of the current over a second time period. A ratio of the first sample voltage and the second sample voltage is indicative of the RC time constant of the electronic circuit line.
