1. A system, comprising:
a host device; and
a memory device configured to store data, the memory device comprising:
a controller;
wherein the controller is configured to receive a first authenticated command from the host device, wherein the first command is associated with enabling forensic tracking and tracing in the memory device;
wherein the controller is configured to parse the authenticated command to obtain tracking and tracing parameters associated with the forensic tracking and tracing;
wherein the controller is configured to transmit an acknowledgement to the host device in response to the first authenticated command;
wherein the controller is configured to receive a second authenticated command, wherein the second authenticated command is associated with performing an operation at a target location in a memory of the memory device;
wherein the controller is configured to verify the second authenticated command and the target location;
wherein the controller is configured to conduct the operation at the target location; and
wherein the controller is configured to record tracking and tracing data associated with the operation conducted at the target location in a secure memory tracing location of the memory of the memory device.
