Abstract
A semiconductor chip apparatus including a memory having a plurality of memory locations, a memory access element, and an integrity check device configured to store a reference value for a check function over values stored in the memory locations and, in a case of write access to a memory location, configured to update a check value with the value to be written by the write access if the check value represents the value stored in the memory location prior to the write access, and configured to compare the reference value with the check value after the check value has been generated and output a signal depending on a result of the comparison.
