A memory circuit that presents input data at a data output promptly on receiving a clock pulse includes upstream and downstream memory logic and selection logic. The upstream memory logic is configured to latch the input data on receiving the clock pulse. The downstream memory logic is configured to store the latched input data. The selection logic is configured to expose a logic level dependent on whether the upstream memory logic has latched the input data, the exposed logic level derived from the input data before the input data is latched, and from the latched input data after the input data is latched.

Fast-bypass memory circuit

A memory circuit in which a level of a first data input appears promptly at an output in response to a clock pulse received. The circuit includes a flip-flop triggered by the clock pulse and configured to receive the first data input and drive a second data input. The circuit also includes a first control input driven by the clock pulse, a second control input driven by the flip-flop and selection logic configured to receive the first and second data inputs and the first and second control inputs. The selection logic is configured to drive the output of the memory circuit to the level of the first data input or of the second data input depending on the first and second control inputs.
