Method of reducing disturbs in non-volatile memory

In a non-volatile memory, the displacement current generated in non-selected word lines that results when the voltage levels on an array's bit lines are changed can result in disturbs. Techniques for reducing these currents are presented. In a first aspect, the number of cells being simultaneously programmed on a word line is reduced. In a non-volatile memory where an array of memory cells is composed of a number of units, and the units are combined into planes that share common word lines, the simultaneous programming of units within the same plane is avoided. Multiple units may be programmed in parallel, but these are arranged to be in separate planes. This is done by selecting the number of units to be programmed in parallel and their order such that all the units programmed together are from distinct planes, by comparing the units to be programmed to see if any are from the same plane, or a combination of these. In a second, complementary aspect, the rate at which the voltage levels on the bit lines are changed is adjustable. By monitoring the frequency of disturbs, or based upon the device's application, the rate at which the bit line drivers change the bit line voltage is adjusted. This can be implemented by setting the rate externally, or by the controller based upon device performance and the amount of data error being generated.

Error usage investigation and disposal system

As part of electronically handling a large amount of data (e.g., error messages) generated within, for example, a telephone service provider's billing network, a configuration utility software allows a user to electronically change or update various configuration parameters for another software application, e.g., a loader application, and also to access the performance data generated by the loader application so as to optimize the performance of the loader application in varying data transfer situations. The loader application, in turn, is a computer-based data transfer application that electronically loads a large volume of data, e.g., telecommunication billing data, from one computer into another computer. The loader application thus substantially reduces human involvement during transfers of large amount of data, and thereby also reduces errors typically associated with manual data entries by human data operators. After completion of data transfers, an error handler program facilitates electronic investigation and disposal of errors in the received data, thereby minimizing participation of human operators in the data error rectification process. The reduced reliance on manual identification and correction of data errors thus results in increased accuracy and efficiency in the overall network data management and customer billing operations.

Behavior identification method based on 3D convolution neural network

The invention discloses a behavior identification method based on a 3D convolution neural network, and relates to the fields of machine learning, feature matching, mode identification and video image processing. The behavior identification method is divided into two phases including the off-line training phase and the on-line identification phase. In the off-line training phase, sample videos of various behaviors are input, different outputs are obtained through calculation, each output corresponds to one type of behaviors, parameters in the calculation process are modified according to the error between an output vector and a label vector so that all output data errors can be reduced, and labels are added to the outputs according to behavior names of the sample videos corresponding to the outputs after the errors meet requirements. In the on-line identification phase, videos needing behavior identification are input, calculation is conducted on the videos through the same method as the training phase to obtain outputs, the outputs and a sample vector for adding the labels are matched, and the name of the sample label most matched with the sample vector is viewed as a behavior name of the corresponding input video. The behavior identification method has the advantages of being low in complexity, small in calculation amount, high in real-time performance and high in accuracy.
