Systems for providing access to protected memory

Abstract:

A memory device embodiment may include an array of non-volatile memory cells including a protected memory region. The protected memory region may include a dedicated sub region established by a host. The memory device embodiment may also include a memory controller configured to wipe the protected memory region or execute other security functions by issuing an authenticated data write command to the dedicated sub region of the protected region. Issuing the authenticated data write command may include signing the command with a key shared with the host that established the sub region.
