Abstract
An integrated circuit system (120) includes a memory array (122) storing a configuration data set to configure an integrated circuit. The integrated circuit (121) includes a configuration memory (128) and a configuration controller state machine (126). The configuration controller state machine operates so as to read a read-check signature at a read-check address of the memory array (122) and to compare the read-check signature with a standard signature stored in the integrated circuit (121). If the read-check signature passes the comparison, the configuration controller state machine (126) loads the configuration data set from the memory array to the configuration memory (128) of the integrated circuit.
