Abstract
Provided are a storage device and an operating method of a memory controller. The storage device includes a non-volatile memory that outputs data from selected memory cells based on read voltage information, the read voltage information including a start read voltage, an end read voltage, and a read command. Moreover, the storage device includes a memory controller that determines whether a search region defined by the start read voltage and the end read voltage is within a multi-peak region of a threshold voltage distribution corresponding to a first state of the selected memory cells, based on the search region being within the multi-peak region, change the search region, and based on the search region not being within to the multi-peak region, determine a new read voltage using the search region.
