US Patent Issued to Hewlett Packard Enterprise Development on Jan. 20 for "Compact CAM array for decision tree inference (tree-CAM)" (American, Italian Inventors)

ALEXANDRIA, Va., Jan. 20 -- United States Patent no. 12,531,127, issued on Jan. 20, was assigned to Hewlett Packard Enterprise Development LP (Spring, Texas).

"Compact CAM array for decision tree inference (tree-CAM)" was invented by Giacomo Pedretti (Cernusco sul Naviglio, Italy) and Ron M. Roth (Palo Alto, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: ""Tree-CAMs" constructed to implement decision trees more efficiently are provided-namely with less hardware (i.e., fewer memristors and transistors), less power consumption, and less memristor programming time than existing aCAMs used to implement decision trees. A tree-CAM realizes these optimizations by leveraging a shared comparison sub-circuit tha...
