A data-processing device, such as a memory device, includes a signal generator configured to transmit an enable-signal, and a plurality of circuit elements arranged in an array of plurality of rows spaced along a direction, each of the plurality of the circuit elements configured to receive the enable-signal from the signal generator and to input and output data as a result of receiving the enable-signal. The device also includes an input/out (I/O) interface operatively connected to the plurality of circuit elements and located to propagate data from the I/O interface to the circuit elements in a first direction relative to the direction in which the rows are spaced and receive data propagated from the circuit elements to the I/O interface in a second direction relative to the first direction. The signal generator maintains the direction of enable-signal propagation relative to the direction of data propagation regardless of the direction of data propagation.
