Abstract
A TLB circuit includes a memory circuit and a FAC-CAM circuit, a kind of associative memory. The FAC-CAM circuit receives two data entries, and computes a virtual address while comparing the virtual address with prescribed values stored therein. As the result of the comparison, when the prescribed value which is coincident with the virtual address is found, at least one of a group of coincidence signals is activated and a hit signal is outputted. Thus, the associative memory utilizing the FAC circuit enables a high-speed addition operation and comparison.
