摘要: An integrated circuit device includes a receiver, a register and a clock circuit. The receiver samples data from an external signal line in response to an internal clock signal. The register stores a value that represents a timing offset to adjust the time at which the data is sampled. The clock circuit generates the internal clock signal such that the internal clock signal maintains a controlled timing relationship with respect to an external clock signal. The clock circuit includes an interpolator that phase mixes a set of reference clock signals such that the internal clock signal is phase offset in accordance with the value.

摘要: An integrated circuit device includes a transmitter circuit operable to transmit a timing signal over a first wire to a DRAM. The DRAM receives a first signal having a balanced number of logical zero-to-one transitions and one-to-zero transitions and samples the first signal at a rising edge of the timing signal to produce a respective sampled value. The device further includes a receiver circuit to receive the respective sampled value from the DRAM over a plurality of wires separate from the first wire. In a first mode, the transmitter circuit repeatedly transmits incrementally offset versions of the timing signal to the DRAM until sampled values received from the DRAM change from a logical zero to a logical one or vice versa; and in a second mode, it transmits write data over the plurality of wires to the DRAM according to a write timing offset generated based on the sampled values.

摘要: A bus system comprising a master connected to one or more slave devices via a bus is disclosed. The bus system is able to effectively communicate control information during a calibration phase and to individually determine appropriate timing and/or voltage offsets for each slave device. The offsets are used to optimize transfer timing (including duty cycle characteristics), signal equalization, and voltage levels for data exchanged between the master and the slave devices.
