A method includes configuring a first set of blocks of a plurality of blocks of an IC chip as secure data blocks, and configuring a second set of blocks of the plurality of blocks as non-secure data blocks. The method further includes receiving a test mode entry request in the IC chip. In response to the IC chip receiving the test mode entry request, carrying out a data-initialization operation on the plurality of blocks independently of whether any blocks of the plurality of blocks are configured as the secure data blocks or the non-secure data blocks. An IC chip data output is disabled during the data-initialization operation.
