STORAGE DEVICE AND OPERATING METHOD OF MEMORY CONTROLLER

This abstract first appeared for US patent application 20240427498 titled 'STORAGE DEVICE AND OPERATING METHOD OF MEMORY CONTROLLER



Original Abstract Submitted

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.
