Filed: 2020-06-11
Abstract: Aspects of a storage device including a memory and a controller, capable of preventing retransmission of set feature commands having the same read voltage threshold offset for the same die are provided. When the controller receives a first read command for data stored in the memory, the controller identifies a first parameter for modifying a first read threshold, and executes a first set feature command for modifying the read threshold based on the first parameter. Subsequently, when the controller receives a second read command for the data stored in the memory from a host device, the controller identifies a second parameter for modifying a second read threshold, and determines a time point at which the first parameter and the second parameter are equal to each other. When the parameters are equal to each other, the controller suppresses execution of a second set feature command for modifying the second read threshold.
