Abstract
A content addressable memory (CAM) for use with a microprocessor allows comparison of the contents of the memory with input data. The CAM further allows certain bits of input data to be ignored from comparison. This feature allows certain bits, such as a bit indicating whether read or write access is allowed to certain information, to be ignored when the system is, for example, in a supervisory mode. Also disclosed is a method of precharging a hit line, which indicates whether or not a match was found in memory during the comparison, in order to increase the speed of the comparison process.
