A programming method for a memory device is disclosed. The programming method comprises moving a plurality of first charge carriers at a shallow energy level to a channel in a substrate layer before a fine programming operation for a first word line, wherein the plurality of first charge carriers at the shallow energy level correspond to a memory cell to be programmed.

A method and a system of using machine learning to automatically generate a reference data structure for a K-anonymity model. A vector space is generated from reference text data, where the vector space is defined by numerical vectors representative of semantic meanings of the reference text words. Input text words are converted into numerical vectors using the vector space. Word clusters are formed according to semantic similarity between the input text words, where the semantic similarity between pairs of input text words is represented by metric values determined from pairs of numerical vectors. The word clusters define nodes of the reference data structure. A text label is applied to each node of the reference data structure, where the text label is representative of the semantic meaning shared by elements of the word cluster.
