System for forensic tracing of memory device content erasure and tampering
A system for providing forensic tracing of memory device content erasure and tampering is disclosed. The system uses a special command that enables forensic tracing in a secure memory device. Once the forensic tracing is enabled, firmware of the memory device tracks the data stored on the memory device.

The firmware confirms that the forensic tracing is enabled, and a target protection region is defined. Once an authenticated command for an operation to access, modify, or erase data of the memory device is received from a host, the system enables the operation to proceed. The system creates a trace of the operation and the metadata of the target region that is modified within a secure memory region of the memory device that is not addressable by the host device. |

Reading compressed data directly into an in-memory store
Example solutions read compressed data from a file in persistent storage, directly into an in-memory store without decompression.
