    Abstract: In a high speed memory subsystem differences in each memory device's minimum device read latency and differences in signal propagation time between the memory device and the memory controller can result in widely varying system read latencies. The present invention equalizes the system read latencies of every memory device in a high speed memory system by comparing the differences in system read latencies of each device and then operating each memory device with a device system read latency which causes every device to exhibit the same system read latency.

    Abstract: A counter circuit includes a series of registers driven by two phase shifted clocks. A clock generator in the counter circuit generates four asymmetrical clock signals to drive each of the registers. The registers are formed from input and output stages, each having two sets of switches. The first set of switches in each stage provides a supply voltage to a stage output in response to the asymmetrical clocks. The second set of switches supply ground to the stage output in response to the asymmetrical clocks. To accelerate response of the switching circuits, isolation switches decouple the first set of switches in each pair from the stage output during switching of the second set of switches, thereby removing loading of stage output by the second set of switches.
