  • Publication number: 20080002516
    Abstract: A single chip dynamic random access memory has a memory core, including dynamic random access memory cells, and a clock receiver circuit to receive an external clock signal. A delay locked loop circuit is coupled to the clock receiver circuit. In a first power mode, the delay locked loop circuit and the clock receiver circuit are turned on. Power consumption in the first power mode is less than that consumed while in an active mode. In a second power mode, the delay locked loop circuit is turned off. The memory is configured to receive a command that specifies a power down mode, to turn off the delay locked loop circuit in response to the command that specifies the power down mode, and to operate the memory device in a standby power mode. The delay locked loop circuit and the clock receiver circuit are turned on in a standby mode.

  • Publication number: 20070242532
    Abstract: An integrated circuit memory device includes a first set of pins and a memory core. The first set of pins receive, using a clock signal, a write command and a read command. Control information is issued internally in response to the write command after a predetermined delay time transpires following receipt of the write command, the control information initiating the write operation in the memory device. A second set of pins output the read data after a first delay time transpires from when the read command is received. Each pin of the second set of pins outputs two bits of read data during a clock cycle of the clock signal. The second set of pins also receive write data after a second delay time has transpired from when the write command is received. The second delay time is based on the first delay time.

  • Publication number: 20070201280
    Abstract: A method and system for transferring information within a computer system is provided. The system includes a memory device that has a lower power mode in which data transfer circuitry is not driven by a clock signal, and a higher power mode in which data transfer circuitry is driven by a clock signal. The system further includes a memory controller that sends control signals to the memory device to initiate a data transfer transaction. The memory device receives the control signals asynchronously, and assumes the second mode in response to one of the control signals. While the memory device is in the second mode, the memory controller sends a control signal to identify a particular clock cycle. The memory device synchronously transfers the data. The memory device determines when to begin the data transfer based on the identified clock cycle and the type of data transfer that has been specified.

  • Publication number: 20070159912
    Abstract: An integrated circuit memory device having delayed write command processing includes a first set of pins coupled to a memory core, the first set of pins to receive a row address followed by a column address. A second set of pins, coupled to memory core, are used to receive a sense command followed by a write command. The sense command specifies the sensing of a row of memory cells identified by the row address, and the write command specifies that the memory device receive write data and store the write data at a column location identified by the column address. The write command is posted internally to the memory device after a first delay has transpired from when the write command is received at the second set of pins.

  • Publication number: 20070147155
    Abstract: A dynamic random access memory device includes banks of dynamic memory cells. The device performs a refresh operation in response to receiving a self refresh command, by refreshing rows of the memory cells located in each of the banks. Further, a refresh frequency for the refresh operation is selected such that the refresh frequency is minimized to conserve power consumed by the memory device while being sufficient to refresh the rows of the memory cells.

  • Publication number: 20060059299
    Abstract: A memory device has interface circuitry and a memory core which make up the stages of a pipeline, each stage being a step in a universal sequence associated with the memory core. The memory device has a plurality of operation units such as precharge, sense, read and write, which handle the primitive operations of the memory core to which the operation units are coupled. The memory device further includes a plurality of transport units configured to obtain information from external connections specifying an operation for one of the operation units and to transfer data between the memory core and the external connections. The transport units operate concurrently with the operation units as added stages to the pipeline, thereby creating a memory device which operates at high throughput and with low service times under the memory reference stream of common applications.

  • Publication number: 20060022724
    Abstract: A method and circuit for achieving minimum latency data transfer between two mesochronous (same frequency, different phase) clock domains is disclosed. This circuit supports arbitrary phase relationships between two clock domains and is tolerant of temperature and voltage shifts after initialization while maintaining the same output data latency. In one embodiment, this circuit is used on a bus-system to re-time data from receive-domain, clocks to transmit-domain clocks. In such a system the phase relationships between these two clocks is set by the device bus location and thus is not precisely known. By supporting arbitrary phase resynchronization, this disclosure allows for theoretically infinite bus-length and thus no limitation on device count, as well as arbitrary placement of devices along the bus. This ultimately allows support of multiple latency-domains for very long buses.
