    摘要: An analog mixed digital DLL includes a digital mode controller and an analog mode controller. The digital mode controller compares phases of delay clock signals outputted from a plurality of delay blocks and a first clock signal, detects an initial locking point, selects one delay clock signal at the detected initial locking point and controls the operation of the delay clocks. The analog mode controller compares the phase of the delay clock signal selected by the digital mode controller and the phase of a first clock signal. The analog mixed digital DLL can provide an externally inputted first control voltage or a second control voltage to the delay blocks in accordance with the digital and analog operation modes and implements a wide band frequency operation, has a short duration of jitters, prevents a multi-locking during a wide band frequency operation and decreases a current consumption.

    摘要: A system having serially connected memory devices in a ring topology organization to realize high speed performance. The memory devices have dynamically configurable data widths such that the system can operate with up to a maximum common number of active data pads to maximize performance, or to operate with a single active data pad to minimize power consumption. Therefore the system can include a mix of memory devices having different data widths. The memory devices are dynamically configurable through the issuance of a single command propagated serially through all the memory devices from the memory controller in a broadcast operation. Robust operation of the system is ensured by implementing a data output inhibit algorithm, which prevents valid data from being provided to the memory controller when read output control signal is received out of its proper sequence.

    摘要: A dynamic random access memory (DRAM) device has an array of DRAM cells of rows by columns. Each DRAM cell of the array is coupled with a wordline of a corresponding row and a bitline of a corresponding column. An entry into and an exit from the self-refresh mode are detected by a mode detector and a self-refresh mode signal is provided. An oscillation circuit generates in response to the self-refresh mode signal generates a basic time period. A first frequency divider/time period multiplier changes the basic time period in accordance with a process variation factor relating to the DRAM device. A second frequency divider/time period multiplier further changes the changed time period in accordance with a temperature change factor relating to the DRAM device. In the self-refresh mode, data stored in the DRAM cells is refreshed. In accordance with the two factors, the DRAM devices perform and achieve reliable self-refresh for variable DRAM cell retention time.
