1. A method of operating a field programmable gate array (FPGA), comprising: initiating an active mode for the FPGA; applying a read voltage to a programmable resistive random access memory (RRAM) element of an RRAM configuration cell of the FPGA, wherein the read voltage is insufficient to appreciably modify an existing configuration state of the RRAM configuration cell; and measuring a signal output contact connected to the RRAM configuration cell for existence of a data signal on the signal output contact.
