摘要： A regulated charge pump circuit (Fig. 1) having two-way switching means (36, 38) that switches between a first feedback pathway that provides a precise and stable voltage output and a second feedback pathway that provides a regulated voltage output with low current consumption from the power source. The first feedback pathway (30, 32, 36) maintains a precise voltage output by regulating a pass device (22) that draws current to the voltage output. The second feedback pathway (30, 34, 38) regulates the voltage output by controlling the connection (18) of a clock input (14) to the charge-pump (10). A variable resistor (28) is used to set the regulated level of the voltage output. A digital-to analog converter (Fig. 4) is formed by using a combination logic circuit (42) to convert a digital input signal (40) to control signals (51-56) for the variable resistor.

摘要： A DAC-based voltage regulator system for a non-volatile memory device comprises a charge pump circuit having an enable input and a voltage output node. A voltage-to current converter has an input coupled to the voltage output node and an output coupled to a virtual ground node. A current source is coupled to the virtual ground node and sinks one of a plurality of currents in response to states of a plurality of digital input signals. A transconductance amplifier has an inverting input at the virtual ground node, a non-inverting input coupled to a reference voltage potential, and an output. A comparator has a first input coupled to the output of the transconductance amplifier, a second input coupled to a reference voltage potential, and an output coupled to the enable input of said charge pump.

摘要： A regenerative clock repeater (Fig. 5; 700) comprises an edge detector (Fig. 6; 500) and an output driver means (706) to produce the clock signal (CK) by recovering its high logical level and low logical level. The output driver means further comprises a pull-up (706A) and a pull-down (706B) circuitry adapted to receive a pair of control signals (PULL-UP#, PULL-DOWN#). These control signals are generated by the edge detector to sense the rising edge and falling edge of the clock signal. Inside the edge detector, a pair of threshold level detectors (540, 550) detect a high and a low logical level of the clock signal and inputs the results to a combination of logic gates (562, 564, 568, 570) and a latch (566) to keep the locations of the signal markers fixed. These fixed-location of control signals trigger the output driver means to recover the high logical level and the low logical level of said clock signal.

摘要： An embedded circuit (14) in a memory device (10) is used in place of an external test device to perform time-consuming tasks such as voltage verification during the setting of reference cells (20). An external test device (16) programs at least one reference cell (22) to a predetermined value. The embedded circuit uses the cell (22) programmed by the external device as a comparative reference to program additional reference cells (20).
