    Abstract: A time manager controls one or more timing functions on a circuit. The time manager includes a data storage and a time calculator. The data storage device stores a first indication of a performance characteristic of a memory cell at a first time. The data storage device also stores a second indication of the performance characteristic of the memory cell at a second time. The time calculator is coupled to the data storage device. The time calculator calculates a time duration between the first time and the second time based on a change in the performance characteristic of the memory cell from the first indication to the second indication.

    Abstract: An example communications apparatus includes a plurality of communicatively-interconnected communication domains and an electronic switch, integrated as part of a first domain of the plurality of communicatively-interconnected communications domains. The electronic switch effects secure communications of data over the one or more channels specific to the first domain, by using a first circuit and a second circuit. The first circuit is used to obtain and process sampled channel properties associated with the one or more channels specific to the first domain. The second circuit is used to generate, in response to the first circuit, a domain-specific code that is generated pseudo-randomly using the processed sampled channel properties, the domain-specific code being used for coding data conveyed over the one or more channels specific to the first domain.
