Abstract:
A data storage method applying to the phase change memory and a phase change memory are provided. After obtaining to-be-stored data, the phase change memory generates an erase pulse signal and a write pulse signal according to the to-be-stored data. The to-be-stored data is multi-bit data. The write pulse signal is a signal including at least two consecutive pulses with a same amplitude. The amplitude of the at least two consecutive pulses is a value determined according to the to-be-stored data. Then, the phase change memory applies the erase pulse signal to a storage unit of the phase change memory to allow the storage unit to switch to a crystalline state. Further, the write pulse signal is applied to the storage unit to allow the storage unit to switch to an amorphous state corresponding to a first resistance value, where the amorphous state represents the to-be-stored data.
Abstract:
A latch and a D flip-flop, where the latch includes a switch, a resistive random-access memory, a bleeder circuit, and a voltage converter. The voltage converter is configured to output an output signal of the latch according to an input signal of the latch when the switch is in an on state, where the output signal remains consistent with the input signal. When the switch changes from the on state to an off state, the resistive random-access memory is configured to work together with the bleeder circuit to enable an output signal of the latch when the switch is in the off state to remain consistent with an output signal of the latch when the switch is in the on state, thereby implementing a nonvolatile latching function. A circuit structure of the latch is simple and integrity of an existing logic circuit can be improved.

Abstract:
A positioning method based on a visible light source, a mobile terminal, and a controller. The method includes acquiring, by a visible light source controller, geographical position attribute information of a position at which a visible light source array is located, determining, by the visible light source controller according to a preset correspondence between geographical position attribute information of a position at which a visible light source array is located and a visible light source array pattern, a visible light source array pattern corresponding to the acquired geographical position attribute information, and controlling, by the visible light source controller according to the determined visible light source array pattern, the luminance state of each visible light source included in the visible light source array. Hence the method reduces the complexity of a positioning process.
Abstract:
Embodiments of the present invention disclose a method for switching an NC link, a processor system, and a node, where the processor system includes more than two nodes capable of communicating with each other, each node includes a node controller NC chip, a host bus adapter HBA apparatus, and at least one CPU, the NC chip is connected to each CPU in a node where the NC chip is located, and the HBA apparatus is connected to each CPU in a node where the HBA apparatus is located; an NC link borne by the NC chip is corresponding to an HBA link borne by the HBA apparatus. By using an HBA apparatus to deploy a redundant link, the cost of deploying the redundant link is reduced effectively under a premise of ensuring the reliability of the processor system.
