1. A system, comprising:
a host device; and
a memory device coupled with the host device, wherein the memory device is operable to:
exchange data with the host device;
determine, after exchanging data with the host device, a value of a parameter that indicates a health status associated with operability of the memory device;
transmit, via a via a Joint Test Action Group (JTAG) interface of the memory device, an indication of the value of the parameter to a device that is different than the host device and external to the memory device, wherein the host device is operable to alter a configuration of the system based at least in part on the health status associated with operability of the memory device, and wherein the device comprises a controller that is coupled with the memory device via the JTAG interface of the memory device and is coupled with the host device via a second interface, and wherein the controller is operable to:
receive the indication of the value of the parameter via the JTAG interface; and
transmit, in response to receiving the indication, a second indication of the value of the parameter to the host device via the second interface;
receive, from the host device in response to the indication of the value of the parameter, an indication of an adjustment for a second parameter for the memory device;
adjust a value of the second parameter based at least in part on the indication of the adjustment; and
operate based at least in part on the adjusted value of the second parameter.
