1. A data storage device, comprising:
a memory device, wherein the memory device comprises:
a first namespace accessible via a first interface; and
a second namespace accessible via a second interface, wherein the first namespace and the second namespace are distinct; and
a controller coupled to the memory device, wherein the controller is configured to:
receive a first request to write data to the memory device, wherein the first request is transmitted through the first interface;
write data to the memory device; and
receive a second request to read data from the memory device, wherein the second request is received through the second interface, and wherein the second interface is physically distinct from the first interface, and wherein the second namespace is a secure namespace that can only be read through requests transmitted through the second interface.
