Abstract

Described are embodiments of an invention for blocking write access to memory modules of a solid state drive. The solid state drive includes a controller access module or a memory access module that controls write access to the solid state drive and the memory modules of the solid state drive. Upon determining that a memory module has failed, the failed memory module or the entire solid state memory device is configured to be read only to prevent an errant write of data over critical data. Further, a failed memory module, or solid state device memory having a failed memory module, may be replaced upon failure.
