Abstract: Described apparatuses and methods enable a system including at least one memory device to load different address scramble patterns on dies of the memory device. The address scramble patterns may include the logical-to-physical conversion of rows in the memory device or the memory dies. In aspects, the apparatuses and methods can change the address scrambles at different intervals, such as after a power reset or when the data stored on the memory device is invalid, not current, flushable, or erasable. The described aspects may reduce effectiveness of usage-based disturb attacks used by malicious actors to discover a layout of a type of particular memory device or memory die.
