Abstract

An apparatus (4) comprises memory access circuitry (12) to control access to data stored in a memory; and memory integrity checking circuitry (20) to verify integrity of data stored in the memory, using an integrity tree (26) in which the association between parent and child nodes is provided by a pointer. This helps to reduce the memory footprint of the tree.
