A method for securely handling processing of information may include deactivating within a chip, at least one of a plurality of functions that accesses an on-chip memory and generates output data from input data during operation of the chip. Configuration settings that provide maximum performance when accessing the on-chip memory may be determined using an enabled one of the plurality of functions. Access to the on-chip memory may be enabled using the determined configuration settings during the operation of the chip. Access to the on-chip memory by the plurality of functions that accesses the on-chip memory and generates the output data from the input data may be activated during operation of the chip. The on-chip memory may be accessed using the determined configuration settings by the at least one of the plurality of functions subsequent to the activating.
