AI Technical Summary
Existing ternary content-addressable memories (TCAMs) have shortcomings in terms of storage density and power consumption, and the matching bit count cannot accurately represent the correlation between values, resulting in decreased accuracy.
By employing multiple content-addressable memory cells and electrical characteristic detection circuits, mismatched output signals with different current intensities are generated by adjusting the voltage of the search data and the threshold voltage of the memory cells to represent differences in the degree of similarity.
It increases the storage density of the memory, reduces power consumption, and can more accurately represent the correlation between values, thus improving the accuracy of data retrieval.
