A tester unit for evaluating data integrity of a block of data is described. The tester unit comprises a checksum determination facility adapted for deriving a checksum value from a block of data stored in a memory, and a checksum evaluation facility adapted for comparing the derived checksum value with a predetermined checksum value, and for initiating a reload of the block in case the derived checksum value differs from the predetermined checksum value.
