Abstract
A memory device and a method of operating the same are provided. The memory device may include a peripheral circuit configured to perform a plurality of program loops and program a page selected from among the plurality of pages, wherein the peripheral circuit may count a number of memory cells whose threshold voltages have increased up to a first target voltage, among a part of memory cells included in the selected page, and may perform a current sensing check operation of determining whether a verify operation performed in a previous program loop has passed or failed, and a control logic circuit configured to control the peripheral circuit so that the current sensing check operation is performed when the number of memory cells whose threshold voltages have increased up to the first target voltage, is equal to or greater than a reference number of memory cells.
