A method of eliminating signal contention during reconfiguration of a programmable logic device includes the steps of: arranging a plurality of memory cells in sets and selectively programming the memory cells one set at a time, either in a first direction or a second direction. A structure for providing that selective programming includes a plurality of synchronous flip-flops, and a plurality of associated two-input multiplexers. A control signal in a first logic state provided to the multiplexers provides a first signal propagation direction through the flip-flops, whereas the control signal in a second logic state provides a second signal propagation direction through the flip-flops.
