    摘要: In this circuit, an external voltage source is supplied or down converted in response to a normal operating mode to provide the internal voltage source of a first level to the internal circuit. The external voltage source is converted to a voltage of a second level, lower than the first level, in response to a low consumption power mode having a complementary relation with the normal mode.

    摘要: A negative voltage generator is controlled responsive to a word line precharge signal. Voltage fluctuations in a negatively biased word line scheme are reduced by using a kicker circuit to provide a predetermined amount of negative charge to shut off a word line during a precharge operation. The negative voltage generator includes first and second negative charge pumps. The second charge pump is activated responsive to the word line precharge signal. A negative voltage regulator can be used to regulate a negative voltage signal. A level shifter uses two voltage dividers and a differential amplifier to reduce response time, output ripple, and sensitivity to process and temperature variations. A negative voltage regulator cancels ripple from a charge pump to provide a stable negative bias voltage and reduce the amount of charge needed to precharge a word line.

    摘要: A memory device utilizing a negatively biased word line scheme diverts word line discharge current from the negative voltage source during a precharge operation, thereby reducing voltage fluctuations and current consumption from the negative voltage source. A main word line, sub-word line, word line enable signal, or other type of word line is coupled to the negative voltage source during a precharge operation. The word line is also coupled to a second power supply during the precharge operation, and then uncoupled from the second power supply after most of the word line discharge current has been diverted. The negative voltage source can then discharge and maintain the word line at a negative bias.

    摘要: A voltage detecting circuit includes a first voltage generator that provides a reference voltage, a second voltage generator that provides a comparison voltage in response to a boosted voltage, and a differential amplifier that provides an amplified difference signal to generate a voltage level detection signal in response to a voltage difference between the reference voltage and the comparison voltage. A bypass circuit is coupled to the amplified signal to detect a target VPP level suitable for a test mode by providing a current path in response to the comparison voltage when the comparison voltage reaches a predetermined level. The voltage detecting circuit thereby allows a precise and stable detecting operation to be performed regardless of the operation mode or process or temperature variations.

    摘要: A bidirectional input/output buffer operates in a current mode to increase the data transfer rate between devices connected by a bidirectional transmission line. The buffer includes an output current source for generating an output current responsive to a data output signal. The output current is combined with an output current indicative of a data input signal received from another device over a transmission line, thereby forming a mixed current signal. The data input signal is restored from the mixed signal by a restoring circuit that compares the mixed signal to a reference current that depends on the value of the data output signal. The restoring circuit includes a current mirror and a reference current source that generates a reference current in response to the data output signal. To provide additional performance, an embodiment of a bidirectional input/output buffer utilizes a switchless structure having two comparators that compare the mixed signal to two different reference signals, thereby generating two comparison signals. A selector circuit selects one of the two comparison signals as the restored data input signal responsive to the data output signal.
