Abstract

A host including a controller configured to be connected to a storage device separate from the host. The controller is configured to maintain random access memory (RAM) code on the host, the RAM code configured to provide a destructive function, temporarily load the RAM code onto a volatile memory in the storage device during a manufacturing process, wherein the loaded RAM code, when executed by a processor in the storage device, is configured to cause the processor in the storage device to perform a destructive function on the storage device, and remove the loaded RAM code from the volatile memory after the manufacturing process, wherein the destructive function is unable to be performed by the processor when the loaded RAM code is removed from the volatile memory.

First claim

What is claimed is:

1. A host computing device comprising:
a controller configured to be connected to a data storage device separate from the host computing device and to:
maintain random access memory (RAM) code on the host device, the RAM code including instructions for performing a destructive function on the data storage device;
temporarily load the RAM code onto a volatile memory of the data storage device during a manufacturing process, wherein the loaded RAM code, when e…
