Abstract: A memory device includes a memory cell array configured to store data; and a data output circuit configured to transmit status data to an external device through at least one data line in a latency period in response to a read enable signal received from the external device and transmit the data read from the memory cell array to the external device through the at least one data line in a period subsequent to the latency period.

Abstract: A method of operating a system including a parameter monitoring circuit and a host, includes generating a first parameter applying a first code to a current parameter, wherein a first offset is applied to the first code; generating a first comparison result by comparing the first parameter with a reference parameter value; generating a second parameter applying a second code to the current parameter, wherein a second offset is applied to the second code; generating a second comparison result by comparing the second parameter with the reference parameter value; detecting an error in the current parameter, based on the first comparison result and the second comparison result; and providing a signal based on the error to the host.
