Slave device communicating with master device, and operation method thereof

An electronic device including a memory cell and configured to communicate with an external device through an in-band channel and an out-of-band channel, the electronic device comprising:

• a plurality of status sensors configured to generate a plurality of status values;
• a status manager storing a plurality of device status records respectively including the plurality of status values;
• and
• a device controller configured to perform a read operation or a write operation on the memory cell in response to a command received through the in-band channel,
• wherein the status manager is configured to execute one or more instructions which cause the electronic device to:
• based on receiving a first device status request from the external device through the out-of-band channel, output to the external device through the out-of-band channel a first device status response representing that each of the plurality of device status records is normal, and
• based on receiving a second device status request from the external device through the out-of-band channel, output to the external device through the out-of-band channel a second device status response which includes one or more of the plurality of device status records and which has a packet capacity larger than the first device status response.

A method of operating an electronic device configured to communicate with an external device and storing a plurality of device status records, the method comprising:

• receiving, from the external device, a first device status request comprising a first operation code;
• transmitting, in response to the first device status request, a first device status response having a first packet capacity, wherein the first device status response represents that the plurality of device status records are normal;
• receiving, from the external device, a second device status request comprising the first operation code;
• and
• transmitting, in response to the second device status request, a second device status response having a second packet capacity larger than the first packet capacity, wherein the second device status response comprises one or more of the plurality of device status records.
