Claim 0:
1. A method for booting a processing device, the method comprising:
generating, by a monotonic counter during a first boot phase, a first count value;
transmitting, by the monotonic counter, the first count value to an access control circuit of a memory;
reading, based on the first count value, first data stored in the memory and associated with the first boot phase;
generating, by the monotonic counter during a second boot phase, a second count value greater than the first count, value;
transmitting, by the monotonic counter, the second count value to the access control circuit of the memory;
preventing, by the access control circuit based on the second count value, reading of the first data; and
reading, based on the second count value, second data stored in the memory and associated with the second boot phase.
