Application: Memory device and data searching method thereof (Patent ID: US20230418510A1)

The patent filed by Macronix International Co Ltd describes a data search method for a memory device that involves vectoring search data based on a compression mode, compressing the search data and objects in a database, setting search conditions, searching the objects in the database to find matches with the search data, and recording and outputting the matched objects. The method includes features such as recording object details, outputting original and sorted data, and comparing feature vectors to determine matches.

Additionally, the patent describes a memory device with multiple memory planes, each containing memory blocks with memory cells storing feature vectors. The device encodes search data into search voltages, selects memory blocks for search, and determines matches based on current sensing results. The memory device includes analog-to-digital converters, bit line transistors, and ground select transistors for efficient data search operations. The memory cells have multiple storage states, and the search voltages correspond to the state number of the feature vectors. Each memory plane can store multiple feature vectors of database objects, with dimensions having vector states of up to 3 bits or 8 bits. The controller in the memory device is configured to perform the data search method efficiently based on the recorded compression mode.
