NONVOLATILE MEMORY DEVICE AND OPERATING METHOD OF THE SAME

A non-volatile memory device includes a memory cell array including a plurality of memory cells; a page buffer for performing a plurality of read operations and storing results of the read operations,wherein each of the read operations includes at least one sensing operation for selected memory cells from the plurality of memory cells; a multi-sensing manager for determining a number of sensing operations for each of the plurality of read operations and controlling the page buffer to perform the read operations; and a data identifier for identifying a data state of a bit for the selected memory cells based on the results of the read operations, wherein the multi-sensing manager determines the number of sensing operations for at least one read operation from among the read operations to bedifferent from the number of sensing operations for other read operations from among the read operations. 一种非易失性存储设备包括：包含多个存储单元的存储单元阵列；用于执行多个读取操作并且存储读取操作的结果的页缓冲器，其中，读取操作中的每一个包括用于多个存储单元中的所选择的存储单元的至少一个读出操作；多读出管理器，用于确定多个读取操作中的每一
