摘要： Disclosed is a method of operating a storage controller which communicates with a non-volatile memory device. The method includes outputting a first command including a request for on-chip valley search (OVS) count data of a memory region of the non-volatile memory device to the non-volatile memory device, wherein the OVS count data include a first count value of a first read voltage and a second count value of a second read voltage, receiving the OVS count data from the non-volatile memory device, determining a first error count value for the first read voltage and a second error count value for the second read voltage, based on the OVS count data, and determining a subsequent operation, based on the first and second error count values.

摘要： A storage device and an operating method thereof are provided. The storage device includes a non-volatile memory and a memory controller. The non-volatile memory includes memory blocks each including a word lines. The memory controller determines a word line strength of each of the word lines, adjusts a state count of each of the word lines based on the word line strengths, and adjust a program parameter of each of the word lines to decrease a program time variation between the word lines.

摘要： Described is a storage device which includes a nonvolatile memory device including a plurality of memory blocks, each including a plurality of memory cells connected to a plurality of word lines, and a controller configured to perform a first read operation on memory cells connected to a selected word line included in a selected memory block based on a request of an external host device. The controller is further configured to perform a check read operation that checks a reliability of the memory cells of the selected memory block after performing the first read operation. In the check read operation, the controller is further configured to select and perform one of an actual check and a machine learning-based check.
