A nonvolatile latch circuit and a system on a chip with the same feature detection of change of latch data in an active period to store new data in a latch without an additional data storage time. The nonvolatile latch circuit does not require an additional data storage period but detects change of latch data in the active period to store new data in a nonvolatile latch unit. When power is accidentally off, new data are constantly stored in the nonvolatile latch unit, thereby preventing data loss and improving an operating speed without a booting time for restoring data.
