    摘要: This disclosure provides a method for adjusting system timing in a reconfigurable memory system. In a Dynamic Point-to-Point (“DPP”) system, for example, manufacturer-supplied system timing parameters such as access latency and maximum clock speed typically reflect a worst-case configuration scenario. By in-situ detecting actual configuration (e.g., whether expansion boards have been inserted), and correspondingly configuring the system to operate in a mode geared to the specific configuration, worst-case or near worst-case scenarios may be ruled out and system timing parameters may be redefined for faster-than-conventionally-rated performance; this is especially the case in a DPP system where signal pathways typically become more direct as additional modules are added. Contrary to convention wisdom therefore, which might dictate that component expansion should slow down timing, clock speed can actually be increased in such a system, if supported by the configuration, for better performance.

    摘要: Multiple timing reference signals (e.g., clock signals) each cycling at the same frequency are distributed in a fly-by topology to a plurality of memory devices in various embodiments are presented. These multiple clock signals each have a different phase relationship to each other (e.g., quadrature). A first circuit receives a first of these clocks as a first timing reference signal. A second circuit receives a second of these clocks as a second timing reference signal. A plurality of receiver circuits receive signals synchronously with respect to the first timing reference signal and the second timing reference signal, such that a first signal value is resolved using the first timing reference signal and a second signal value is resolved using the second timing reference signal.
