    摘要: A method and system for cycle accurate data transfer between skewed source synchronous clocks is envisaged. The procedure starts through reset. On reset, both the write and read address registers are set to point to location 0. Source clock is stopped to disable active clock edges to both write and read address registers during the reset procedure. The source clock is subsequently started to deliver active edges to both write and read address registers. On every active source clock edge, data is pushed into the data register based on the location pointed by write address register. On every skewed active clock edge, data is read from the data register based on the address pointed by read address register. Due to the delayed nature of clock reaching the read address register, write address register increments first and stores data into the data register.

    摘要: Integrated circuit devices that operate in different modes. In a low data rate mode, data is transferred between the integrated circuit devices at a low data rate, or no data is transferred at all. In a high data rate mode, data is transferred between integrated circuit devices at a high data rate. A transition mode facilitates the transition from the low data rate mode to the high data rate mode. During the transition mode data is transferred between the integrated circuit devices at an intermediate data rate greater than the low data rate but lower than the high data rate. Also during the transition mode, parameters affecting the transmission of data between the integrated circuit devices are calibrated at the high data rate.

    摘要: Apparatus and methods for operation of a memory controller, memory device and system are described. During operation, the memory controller transmits a read command which specifies that a memory device output data accessed from a memory core. This read command contains information which specifies whether the memory device is to commence outputting of a timing reference signal prior to commencing outputting of the data. The memory controller receives the timing reference signal if the information specified that the memory device output the timing reference signal. The memory controller subsequently samples the data output from the memory device based on information provided by the timing reference signal output from the memory device.

    摘要: Techniques for multi-wire encoding with an embedded clock are disclosed. In one particular exemplary embodiment, the techniques may be realized as a transmitter component. The transmitter component may comprise at least one encoder module to generate a set of symbols, each symbol being represented by a combination of signal levels on a set of wires. The transmitter component may also comprise at least one signaling module to transmit one or more of the symbols over the set of wires according to a transmit clock. The transmitter component may additionally comprise control logic to restrict transmission of first and second subsets of the set of symbols to respective first and second portions of a clock cycle of the transmit clock, such that a signal differential among at least two of the set of wires exhibits a switching behavior that has a same frequency as the transmit clock.

    摘要: A pseudo-dual port memory has a first port, a second port, and an array of six-transistor memory cells. A first memory access is initiated upon a rising edge of a first clock signal received onto the first port. A second memory access is initiated in response to a rising edge of a second clock signal received onto the second port. If the rising edge of the second clock signal occurs within a first period of time, then the second memory access is initiated immediately following completion of the first memory access in pseudo-dual port fashion. If the rising edge of the second clock signal occurs later within a second period of time, then the second memory access is delayed until after a second rising edge of the first clock signal. The durations of the first and second memory accesses do not depend on the duty cycles of the clock signals.
