Abstract
A memory circuit includes an operational memory and a monitor circuit comprising a circuit element in the operational memory and/or a circuit element substantially identical to a corresponding circuit element in the operational memory. The monitor circuit is operative to measure at least one functional characteristic of the operational memory. A control circuit coupled to the monitor circuit is operative to generate a control signal which varies as a function of the measured characteristic of the operational memory. The memory circuit further includes a programmable voltage source coupled to the operational memory which is operative to generate at least a voltage and/or a current supplied to at least a portion of the operational memory which varies as a function of the control signal.
