1. A communication circuit comprising:
a first domain including an input; and
a second domain;
the first and second domains including:
a logical memory including:
a first memory portion in the first domain, the first memory portion including first circuitry having a first threshold voltage; and
a second memory portion in the second domain, the second memory portion including second circuitry having a second threshold voltage that is lower than the first threshold voltage; and
data switching circuitry in at least one of the first domain and second domain, the data switching circuitry coupled to the input and configured to selectively establish a first data path from the input to the first memory portion and to establish a second data path from the input to the second memory portion.
