Abstract: A method and apparatus for controlling access to segments of memory (108) having security data stored therein is provided. A security check unit (304) maintains information for a plurality of segments of memory (108) regarding whether each of these plurality of segments has secure data stored therein. A hint directory (302) maintains information regarding whether any of a plurality of these segments has secure data stored therein. The hint directory (302) is capable of bypassing the security check unit (304) when it receives an address (402) that falls within a plurality of the segments that have been indicated as being free from secure data. When the hint directory (302) determines that a received address (402) falls within one of a plurality of segments that contain secure data, then the address (402) is passed to the security check unit (304) for a closer examination.
