A field programmable gate array (FPGA) having an array of configurable logic blocks (CLBs) which can be partially reconfigured. Each column of CLBs is connected to a corresponding column select line, and each row of CLBs is connected to a corresponding row select line. A rectangular set of CLBs to be reconfigured is selected, wherein the rectangular set of CLBs is defined by the intersection of one or more consecutive columns of CLBs and one or more consecutive rows of CLBs. Column select signals are asserted on the column select lines associated with the one or more consecutive columns of CLBs. Similarly, row select signals are asserted on the row select lines associated with the one or more consecutive rows of CLBs. CLBs which receive both an asserted column select signal and an asserted row select signal are enabled for reconfiguration.
