Abstract
Disclosed are apparatus and techniques for indicating health of a memory system having a controller and nonvolatile memory array. In one embodiment, the invention pertains to a method for indicating health of a removable memory system that is removably coupled with a host device. After the memory system is coupled with a host device, a first health status is output via an external electrical or mechanical interface of the memory system. One or more health metrics of the memory system are monitored. After a first predefined limit is reached with respect to the one or more health metrics, a second health status is output via the external electrical or mechanical interface of the memory system. The first health status differs from the second health status.
