    摘要: A CMOS charge pump with improved latch-up immunity is provided. The CMOS charge pump includes a blocking transistor that disconnects first and second boost nodes from a bulk node in response to a blocking control signal, such that a bulk voltage can be maintained at a predetermined level or higher. The CMOS charge pump in a power-up period first precharges the bulk voltage before the main pump performs a boosting operation and prevents a latch-up phenomenon.

The match line state storing unit is connected to a word line and a match line of the plurality of CAM cells and has a plurality of state cells in which a logic level of stored data is changed according to a logic level of the match line. Errors in the CAM cell array are found by reading data stored in the plurality of state cells. The data stored in the plurality of state cells are matched when there are no errors in the CAM cell array.

The setup and hold measuring circuit generates a reference signal and a data signal in response to an external clock signal in a test mode of operation. The test device receives the data signal in response to a reference signal, and outputs the inputted data signal as a setup and hold determining circuit. One of the reference signal and the data signal is a multiphase signal synchronized with the external clock signal. The setup and hold measuring circuit detects whether the output of the test device indicates a valid value of the data signal, and generates the detected result to the external as a setup/hold timing margin through at least one pad.

    摘要: A negative delay circuit (NDC) has an NDC array operated in a high frequency. The circuit varies a number of unit delay stages at an input stage of the NDC array according to a locking fail signal in a low frequency region. The NDC can carry out a negative delay operation in a wide band even when a number of the stages in the NDC array is small. The present invention decreases a size of a chip, and in addition, reduces an unnecessary current consumption by preventing a locking from re-occurring at a stage in a back portion because the NDC array has a delay value less than one clock.

The method maintains a sufficiently long refresh interval during a refresh operation.
