The memory cell array includes a plurality of memory cells. The read/write circuit is configured to write data to the memory cell array or read data from the memory cell array. The control logic is configured to control the read/write circuit to perform a read/write operation for the memory cell array. The memory cell array includes a plurality of memory blocks, and each of the memory blocks includes a plurality of sub-blocks. During an operation of erasing a sub-block in a memory block, the control logic selects a sub-block to be erased regardless of a sequence in which the sub-blocks have been programmed, and determines an erase verify voltage based on a position of the selected sub-block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor memory device and method of operating the same","description":"A semiconductor memory device includes a memory cell array, a read/write circuit and a control logic.
