Abstract
A semiconductor device includes a memory array including memory blocks; and an operation circuit suitable for performing a program loop and an erase loop on memory cells and selection transistors included in a selected memory block, wherein the program loop is performed by controlling a target threshold voltage value of the selection transistors based on a difference between a cell current value of the selected memory block and a reference cell current value.
