ABSTRACT:
A method, apparatus, and system are provided for implementing a zero-enabled fuse system. An apparatus includes a first set of fuses for activating a first memory portion, and a second set of fuses for activating a second memory portion. The apparatus also includes a controller to control an operation of the first and second set of fuses. The controller is adapted to determine whether a zero address memory location relating to the first memory portion is to be activated based upon an enable fuse. The controller is adapted to also perform a check to determine whether the second set of fuses has been previously activated.
