摘要： A method, system, and device capable of generating one or more clocks internally to detect, sample, and receive synchronous data streams and eliminate the need for corresponding external synchronization clocks for each data stream. One aspect of the clock generator provides a two-stage interpolation system. In a first stage, two clocks are selected which accurately detect a calibration data sample. In a second stage, a single, fine-tuned, clock is synthesized by interpolating the two selected clocks.

摘要： In an embodiment, a memory interface may send an indication that a request is being sent. The indication may be sent to a non-volatile memory via a point-to-point bus between a memory interface and the non-volatile memory. The memory interface may send the request to the non-volatile memory via the bus. The request may include an address that may be used to identify a location for storing or reading data. The non-volatile memory may acquire the request from the bus and process the request. After processing the request, the non-volatile memory may send an indication to the memory interface that indicates the non-volatile memory has a response to send to the memory interface. The memory interface may grant access to the bus to the non-volatile memory. After being granted access to the bus, the non-volatile memory may send the response to the memory interface.

摘要： A memory system and a method for controlling power states of a memory device, or a portion thereof, are provided. The memory system includes memory devices, such as DRAMs, a memory controller, chip select lines, and logic for detecting chip select signals from the chip select lines. Each memory device, or a portion therein, is connected to the memory controller by a chip select line. Each chip select line allows the transmission of a chip select signal to a corresponding memory device, or a corresponding portion of the memory device, to select the corresponding memory device, or a portion thereof, to receive commands. Logic is provided to detect the chip select signal. When the logic detects a chip select signal provided to a corresponding memory device, or a portion thereof, that is in a power state lower than its idle state, the memory device, or a portion thereof, is automatically moved from the lower power state to a higher power state.

摘要： An apparatus and method for accessing a memory. A source address that includes a page address and a page offset is received. The page address requires translation in order to form a first address that can be used to transfer data from a row of memory cells into a sense amplifier array in a memory. The page address is compared to contents of one or more page registers to determine if the data is present in the sense amplifier array as a result of a previous memory access. A second address is asserted to access a portion of the data if the data is determined to be present in the sense amplifier array.

摘要： A method and apparatus for communicating commands and/or data between two different time domains. In one embodiment, multiple memory commands are placed into one or more FIFOs in a manner that specifies the delays that must take place between execution of the different commands. Along with the commands, delay information is placed into the FIFOs, specifying the number of clock cycles, or other form of time delay, that must elapse between execution of a command and execution of a subsequent command. This delay information is used to delay the execution of the subsequent command for the specified time period, while minimizing or eliminating any excess delays. Cue information can also be placed into the FIFOs with the commands to specify which commands must wait for other commands before beginning execution. The delay and cue information is determined and created in the time domain that initiates the transfers. The delays and cueing are executed in the other time domain. Although the different commands may be delivered through different FIFOs and can therefore have unpredictable arrival times with respect to each other, the delay and cueing information maintains the proper execution order and timing between the commands. Interactive control logic at the output of each FIFO uses the timing data to maintain execution in the proper order and with the proper inter-command delays.
摘要翻译：一种用于在两个不同时域之间传送命令和/或数据的方法和装置。在一个实施例中，多个存储器命令以指定在不同命令的执行之间必须发生的延迟的方式被放置到一个或多个FIFO中。与命令一起，将延迟信息放入FIFO中，指定执行命令和执行后续命令之间必须经过的时钟周期数量或其他形式的时间延迟。该延迟信息用于在指定的时间段内延迟后续命令的执行，同时最小化或消除任何多余的延迟。提示信息也可以放在FIFO中，其命令用于指定哪些命令在开始执行之前必须等待其他命令。在启动传输的时域中确定和创建延迟和提示信息。延迟和提示在其他时间域执行。虽然不同的命令可以通过不同的FIFO传递，并且因此可以相对于彼此具有不可预测的到达时间，但延迟和提示信息保持命令之间的正确的执行顺序和定时。每个FIFO的输出端的交互控制逻辑使用定时数据来维持正确顺序的执行和适当的指令间延迟。
