Abstract
There are provided systems and methods that include at least one memory that has a plurality of memory cells. The cells may be disposed in rows and columns. The device can further include a controller that is communicatively coupled to the at least one memory, and the controller may be configured by its hardware topology and its instruction set and/or by a communicatively coupled processor or higher level system or subsystem to maintain data integrity in the at least one memory and/or to prevent or mitigate malicious access patterns that may compromise the at least one memory. The controller may be configured to execute a deterministic protocol in conjunction with or sequentially to a probabilistic protocol to achieve one or more of the above-noted functions.
