Provided are semiconductor devices. A semiconductor device includes processors performing an operation using data stored in a memory; and a memory protector dividing the memory into a first window area and a second window area. The first window area including a first fragment page, which is of a first size. The second window area including a second fragment page, which is of a second size, wherein the second size is smaller than the first size. The memory protector configured to protect the first fragment page and the second fragment page from being accessed by the processors.
