Abstract
Disclosed are systems and methods for diagnosing the health of a plurality of memory cells in a memory array. Diagnostics are initiated from a remote server via an encrypted channel on the memory device embedded in an end-use system. The memory device includes a plurality of memory cells in a memory array. At the remote server, encrypted diagnostics data is received in response to execution of a diagnostics program by the memory device on the plurality of memory cells. The diagnostics data pertains to the health of the memory cells. The encrypted diagnostics data is decrypted into decrypted diagnostics data and the decrypted diagnostics data is analyzed to determine the health of the memory cells. Failure mitigation is performed for the memory device if the analyzing indicates unhealthy memory cells.
