Delay circuits, and related systems and methods are disclosed. In one aspect, a delay circuit is provided that uses logic to delay accurately an output enable signal to reduce or avoid data hazards within a slave device. The delay circuit includes two shift register chains configured to receive an output enable in signal based on a slow clock. A first shift register chain is clocked by a positive edge of a fast clock, and provides a first strobe signal. A second shift register chain is clocked by a negative edge of the fast clock, and provides a second strobe signal. The logic uses the first and second strobe signals, and the output enable in signal, to provide a delayed output enable out signal. The delay circuit provides a highly accurate time delay for the output enable signal to reduce or avoid data hazards in an area and power efficient manner.
