Abstract
Methods, systems, and devices for purging data from a memory device are described. A memory system may receive, from a host system, a command to write data to an address storing an encryption key in a first portion of the memory system that is configured to store secure information (e.g., a Replay Protected Memory Block). The encryption key may be configured to encrypt data associated with the host system that is stored in a second portion of the memory system. The memory system may then receive an indication of a purge command from the host system. The memory system may execute the purge command by transferring data from the first portion of the memory system to a third portion of the memory system configured to store secure information and erasing the data from the first portion of the memory system.
