Abstract
In an embodiment of the invention, a method of providing redundancy in a ternary content addressable memory (TCAM) includes: detecting a defective entry in a ternary content addressable memory (TCAM); marking the defective entry so that the defective entry is visible to a software; and avoiding in using the defective entry. For data that normally would have been written into the defective entry, the data is written into an entry that is subsequent to the defective entry. In another embodiment, the redundancy is provided in a CAM instead of a TCAM.
