Abstract
A nonvolatile analog memory having a floating gate point is disclosed. The analog memory comprises 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 current path of the second current according to a reference current and the first current. Furthermore, while current path of the second current be turned on, the first current be adjusted to equal to the reference current.
