Abstract
A database circuit comprising data circuits and a processing circuit is provided. The data circuits are configured to receive a query data and respectively store a plurality of feature data that form at least one feature data class. The processing circuit is coupled to the data circuits, and configured to match the query data with the feature data to generate matching signals and take a first reference value as a target reference value to compare the matching signals with the target reference value. When at least one of the matching signals is greater than or equal to the target reference value, the processing circuit selects one of the at least one feature data class as a matching result; otherwise, the processing circuit takes a second reference value lower than the first reference value as the target reference value to compare the matching signals with the target reference value.
