ABSTRACT:
A nonvolatile analog memory has a floating gate point. The nonvolatile analog memory includes a first current source, a second current source, and a current adjuster. The first current source generates a first current, and the second current source generates a second current. The current adjuster turns on or turns off a current path of the second current according to a reference current and the first current. Furthermore, when the current path of the second current is turned on, the first current is adjusted according to the second current, such that the first current is equal to the reference current.
