Abstract
Systems and methods are provided for addressing die are inefficiencies associated with the use of redundant ternary content-addressable memory (TCAM) for facilitating error detection and correction. Only a portion of redundant TCAMs (or portions of the same TCAM) are reserved for modified coherency directory cache entries, while remaining portions are available for unmodified coherency directory cache entries. The amount of space reserved for redundant, modified coherency directory cache entries can be programmable and adaptable.
