Each data memory block has a plurality of storage locations and has a particular storage location identified by a same index value. The code memory block has a plurality of code values with a particular code value being associated with the same index value. The particular code value is operable to identify which ones of the particular storage locations associated with the same index value are locked to prevent alteration of contents therein. The particular code value is also operable to identify which particular storage location has been most recently used and which particular storage location has been least recently used of the particular storage locations associated with the same index value.
