Storage device having parameter calibration function, and operating method thereof
An operating method of a storage device includes a controller: receiving read data from a non-volatile memory; measuring a plurality of threshold voltage distributions respectively corresponding to a plurality of memory units of the non-volatile memory, based on the received read data; measuring a distribution variation between the plurality of memory units, based on the measured plurality of threshold voltage distributions; dynamically determining operation parameters for the non-volatile memory, based on the measured distribution variation; and transmitting, to the non-volatile memory, an operate command, an address, and at least one operation parameter corresponding to the address.
