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 operation circuit performs the program loop on the selection transistors so that a difference occurs between threshold voltages of the selection transistors and a target threshold voltage based on a difference between a cell current value of the selected memory block and a reference cell current value.
