According to some embodiments, re-programmable and/or reconfigurable analog circuitry may be provided. A plurality of reference floating-gate transistors are each programmable to be connectable to a plurality of global reference control lines of the analog circuitry to facilitate temperature compensation. In some embodiments, the plurality of analog nonvolatile memory cells are associated with parameter floating-gate transistors. Moreover, the plurality of analog parameter nonvolatile memory cells may be programmed to several orders of parameter magnitude.
