    Abstract: A memory system (100) includes a memory controller (105) that issues command signals and a reference-clock signal to a memory device (110). The edge rate of the reference-clock signal is lower than the bit rate of the command signals, so the memory device multiplies the reference clock signal to develop a command-recovery clock signal with which to sample the incoming command signals. The memory controller issues the command signals as a series of multi-bit command words aligned with edges of the reference-clock signal so that the memory device can use edges of the reference clock signal for command-word alignment.

    Abstract: A method and system provides for execution of calibration cycles from time to time during normal operation of the communication channel. A calibration cycle includes de-coupling the normal data source from the transmitter and supplying a calibration pattern in its place. The calibration pattern is received from the communication link using the receiver on the second component. A calibrated value of a parameter of the communication channel is determined in response to the received calibration pattern. The steps involved in calibration cycles can be reordered to account for utilization patterns of the communication channel. For bidirectional links, calibration cycles are executed which include the step of storing received calibration patterns on the second component, and retransmitting such calibration patterns back to the first component for use in adjusting parameters of the channel at first component.

    Abstract: A method and system that provides for execution of a first calibration sequence, such as upon initialization of a system, to establish an operation value, which utilizes an algorithm intended to be exhaustive, and executing a second calibration sequence from time to time, to measure drift in the parameter, and to update the operation value in response to the measured drift. The second calibration sequence utilizes less resources of the communication channel than does the first calibration sequence. In one embodiment, the first calibration sequence for measurement and convergence on the operation value utilizes long calibration patterns, such as codes that are greater than 30 bytes, or pseudorandom bit sequences having lengths of 2 N -1 bits, where N is equal to or greater than 7, while the second calibration sequence utilizes short calibration patterns, such as fixed codes less than 16 bytes, and for example as short as 2 bytes long.

    Abstract: A memory system having a memory controller and a memory device coupled to the memory controller. The memory controller outputs a write data value to the memory device. The memory device receives the write data value from the memory controller, and compares the write data value with a mask key value. If the write data value matches the mask key value, the memory device does not store the write data value. If the write data value does not match the mask key value, the memory device stores the write data value.

    Abstract: The present embodiments provide a memory system which is configured to send a request from a memory controller to a memory device, wherein the request includes independent activate and precharge commands. The activate command is associated with a row address, which identifies a first row for the activate command. In response to the activate command, the system activates the first row in a first bank in the memory device. Similarly, in response to the precharge command, the system precharges a second bank in the memory device.

    Abstract: Transmission of a signal is scheduled to avoid sending the signal during a designated event associated with another signal. For example, the time at which a signal is transmitted may be scheduled to avoid a turnaround time period of a bidirectional signal path. This technique may be employed, for example, in a memory system where a memory controller communicates with one or more memory devices or memory modules. Here, the memory system may be configured to avoid sending memory request signals during a driver turnaround window corresponding to when a bidirectional memory data interface switches from being driven by the memory controller to being driven by a memory device/module, or vice versa.

    Abstract: A memory system includes a memory controller with a plurality N of memory-controller blocks, each of which conveys independent transaction requests over external request ports. The request ports are coupled, via point-to-point connections, to from one to N memory devices, each of which includes N independently addressable memory blocks. All of the external request ports are connected to respective external request ports on the memory device or devices used in a given configuration. The number of request ports per memory device and the data width of each memory device changes with the number of memory devices such that the ratio of the request-access granularity to the data granularity remains constant irrespective of the number of memory devices.
