A memory device and a word line driver thereof are provided. The word line driver includes a first word line signal generator, a second word line signal generator, a first voltage generator, and a second voltage generator. The first word line signal generator selects one of a first voltage and a second voltage to generate a first word line signal according a control signal. The second word line signal generator selects one of a third voltage and a fourth voltage to generate a second word line signal according the control signal. The first voltage generator provides the second voltage, and the second voltage generator provides the fourth voltage, where the first voltage generator is independent to the second voltage generator.

Memory device and word line driver thereof

An integrated circuit comprises a power supply input pin receiving an off-chip supply voltage having a variable current, an on-chip power source powered by the off-chip supply voltage and providing a regulated current, a memory array, and a set of one or more circuits coupled to the memory array and powered by the regulated current from the on-chip power source. The IC can include control circuitry performing memory operations on the memory array, said control circuitry powered by at least the off-chip supply voltage from the power supply pin.

Power source for memory circuitry

An integrated circuit comprises a power supply input pin for receiving an off-chip supply voltage which can have a variable current, an on-chip power source to be powered by the off-chip supply voltage and which can provide a regulated current, a set of one or more circuits to be powered by at least one of the off-chip supply voltage and the on-chip power source, a configuration memory storing a set of one or more memory settings that indicate whether a circuit of said set of one or more circuits is powered by the on-chip power source, and control circuitry responsive to the at least one memory setting to control whether said circuit of said set of one or more circuits is powered by the on-chip power source.

A power supply apparatus and a method for supplying power are provided. The method includes: providing a first power supply for outputting a first power signal; providing a second power supply for outputting a second power signal; and selectively charging the second power supply by using the first power supply.

Apparatus of supplying power while maintaining its output power signal and method therefor

In one aspect, a charge pump output of a charge pump is coupled to a capacitor of a voltage shifter. The output of the voltage shifter causes pump control logic to enable the charge pump. In another aspect, a transistor in saturation has a drain terminal coupled to a charge pump output and a source terminal coupled to an output mode providing a word line read voltage.

Standby charge pump system

A power supply apparatus and a method for supplying power are provided. The apparatus, for use in a system having a first power signal, includes an assistance unit and a power supply device. The assistance unit outputs at least one maintaining signal according to the first power signal selectively. The power supply device outputs a second power signal, wherein the power supply device maintains the second power signal according to the at least one maintaining signal, for example, in an inactive state, such as an idle or standby state or other suitable timing.
