Abstract:
A data storage device including a solid state memory comprising logical block addresses (“LBAs”) corresponding to boot data accessed by a host during a boot process, and a controller. The controller can be configured to determine the LBAs corresponding to the boot data, and determine whether the solid state memory has reached an end-of-life condition. Upon determining that solid state memory has reached an end-of-life condition, the controller can restrict the host to write to the LBAs corresponding to the boot data during a boot process, and set the solid state memory into a read only mode when the boot process is complete.
