The invention relates to a three-dimensional GIS (Geographic Information System) technology based power grid visualization system and method. The three-dimensional GIS technology based power grid visualization method comprises the steps of: dividing models to be uploaded into different model upload sub-tasks based on different types of objects included in a scene to be uploaded, and calling model documents of the multiple sub-tasks in a parallel manner through a multi-thread way to improve an uploading speed; and meanwhile, on the basis of dividing the uploading tasks into different model uploading sub-tasks based on the type of the uploaded objects, only reading the model document of the objects of each type for once, wherein the repeated use of each model document is not limited to the uploading task of one client; and different clients can multiplex the read model documents. Therefore, the three-dimensional GIS (Geographic Information System) technology based power grid visualization system and method, disclosed by the invention, have the advantages of giving a full consideration to the characteristics of limited type and relative consistent specification of power devices, avoiding repeated reading of the model documents of the same type, obviously improving the uploading efficiency, guaranteeing rapid uploading and guaranteeing real-time browsing of the clients.

In order to charge a pair of ferroelectric capacitors that constitute a memory cell, a voltage setting circuit sets a voltage difference between both ends of the ferroelectric capacitors to be lower than a coercive voltage in a read operation. A differential sense amplifier amplifies a voltage difference between bit lines generated in accordance with a difference in charging amounts of the ferroelectric capacitors. A voltage difference between both ends of the ferroelectric capacitor being charged is lower than the coercive voltage; accordingly, a polarization vector of the ferroelectric capacitor is inhibited from reversing. As a result, the ferroelectric material can be inhibited from deteriorating owing to the read operation, thereby eliminating the restriction on the number of times of read operations in the ferroelectric memory.

A method of determining a default read voltage of a non-volatile memory device which includes a plurality of first memory cells, each of which stores a plurality of data bits as one of a plurality of threshold voltages corresponding to a plurality of logic states, includes programming a first data to the first memory cells so that the logic states of the first memory cells are balanced or equally used. The method includes applying a first default read voltage included in default read voltages to word lines coupled to the first memory cells, and measuring a first ratio of first on-cells, each of which has a threshold voltage smaller than or equal to the first default read voltage, among the first memory cells, and modifying the first default read voltage based on the first ratio and a first reference value corresponding to the first default read voltage.

The embodiment of the invention discloses an acceleration method and device of data operation, a terminal and a readable storage medium. The method comprises the steps of reading a data group to be operated in each storage unit, buffering the read data group to a GPU and calling the GPU to carry out parallel operation on the buffered data group, wherein each storage unit stores a data group formedby data elements at the same position in each matrix data to be calculated. Compared with the prior art, in the operation process of the embodiment of the invention, the number of times of data reading in the operation process is reduced, at the same time, the operation speed of the data to be calculated can be effectively improved, in addition, since the operation process is transferred from a CPU to a GPU in the embodiment of the invention, the occupation rate of the CPU also can be reduced, and the normal operation of the terminal is ensured.
