Abstract
Methods, systems, and devices for address obfuscation for memory are described. A mapping function may map a logical address of data to a physical address of a memory cell. The mapping function may be implemented with a mapping component that includes mapping subcomponents. Each mapping subcomponent may be independently configurable to implement a logic function for determining a bit of the physical address. The mapping function may vary across memory devices or aspects of memory device, and in some cases may vary over time.
