Abstract
A memory system may include a memory device including a plurality of memory cells, and a controller suitable for controlling the memory device to perform a first read operation by applying a first read voltage to a target memory cell in which data corresponding to a read command provided from a host is stored. When the number of fail bits in first read data read through the first read operation is greater than or equal to a preset threshold value, the controller may check outside temperature recorded in a temperature table based on real time clock (RTC) information and country information which are provided from the host, set a second read voltage based on the outside temperature and a read voltage table, and control the memory device to perform a second read operation by applying the second read voltage to the target memory cell.
