    Abstract: 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.

    Abstract: The present invention relates to serial asynchronous transmission of data of fixed length in which a start bit and a stop bit are inserted at the head and tail, respectively, of the data. The insertion of a fixed bit having a predetermined logical value every predetermined number of bits of the data allows an idle state period to be reduced up to the predetermined number of bits plus 1 bit, resulting in considerable improvement in transmission efficiency.

    Abstract: A method and apparatus for determining the appropriate timing interval for each bit or data symbol in serial data communications. A sending device transmits a predetermined bit sequence, such as a binary pattern corresponding to one byte, either on its own initiative or in response to an action of a receiving device. A microprocessor in the receiving device measures a calibration time interval between the leading edge of a start bit and a subsequent marker transition, either between subsequent data bits or between the final data bit and the stop bit. This measured interval may be mathematically converted to units useful to calibrate a function or device that conducts input/output operations. Optionally, the process may be repeated periodically to compensate for clock rate drift. This invention may be used for autobaud data rate detection, or matching the actual data rate of a remote serial device, and permits accurate communications without precision timing references.
