Detailed Description

A replaceable entry is a basic entry in a 2d table-like structure that needs to have replacement functionality.

This entry is located in a specific row and column of the table (set and way in cache nomenclature), which are stored within the entry itself.

It contains the replacement data pointer, which must be instantiated by the replacement policy before being used.
