Apparatus with loopback control mechanism and methods for operating the same

An apparatus, comprising:

• a communication interface configured to communicatively couple the memory device to an external device;
• and
• a memory controller coupled to the communication interface and configured to:
• implement a loopback mechanism for testing a communication link between the apparatus and the external device, wherein the loopback mechanism is initiated when the memory device sends a loopback indicator for the external device to operate as a secondary device that retransmits a message sent from the memory device;
• monitor one or more parameters associated with communicating with the external device;
• based on the monitored one or more parameters, detect that the external device is erroneously and unilaterally implementing the loopback mechanism before or without the loopback indicator is sent;
• and
• implement a response to detecting that the external device is erroneously functioning as the secondary device.

A method of operating a memory device that includes memory cells configured to store data, the method comprising:

• implementing an initial instance of a transient scan in response to a power-on event for transitioning the memory cells from a stable state to a transient state, the transient state representing a physical state of the memory cells that corresponds to a lower error rate than the stable state in providing access to the stored data,
• wherein implementing the transient scan is implemented according to a variable ganging size set to a first number of blocks,
• wherein implementing the transient scan includes reading from the memory cells with a ganged reset read (GRR) that reads a number of memory blocks according to the variable ganging size and without providing read results to an external circuit;
• dynamically adjusting the variable ganging size to a second number of blocks, different from the first number, after initially implementing the transient scan;
• and
• implementing a subsequent instance of the transient scan according to the second number of blocks.
