A data storage device having mediametric properties used as a source of data for cryptoprocessing keys. A memory array is formed by a plurality of memory cells, each cell containing a level of trapped charges that are difficult or impossible to set to a specific value, but which may be read relatively precisely. The levels of trapped charges are read from selected cells. Data relating to the level of the trapped charges is used to produce the cryptoprocessing keys. In addition, data relating to the charge levels in a memory array is used in generation of random numbers. When a random number is desired, data is written to selected cells of the memory array in order to establish random charge levels in the cells. The data is then read from the selected cells and processed to yield a random number.

A controller offers various security modes for protecting program code and data stored in memory and ensuring that the protection is effective during all normal operating conditions of the controller. The controller includes configuration settings that segment program memory into a boot segment, a secure segment and a general segment, each with a particular level of security including no enhanced protection. The boot code segment (BS) is the most secure and may be used to store a secure boot loader. The secure code segment (SS) is useful for storing proprietary algorithms from third parties, such as algorithms for separating ambient noise from speech in speech recognition applications. The general code segment (GS) has the least security. The controller is configured to prevent program flow changes that would result in program code stored in high security segments from being accessed by program code stored in lower security segments. In addition, the processor may be configured to have associated secure data portions of both program memory, such as flash memory, and random access memory (RAM) corresponding to the BS, SS and GS. Attempts 15 to read data from or write data to the program memory or RAM associated with a higher security level from a lower security level are prevented from occurring.
