Abstract
Methods and apparatus for enabling a power up process of a non-volatile memory to occur efficiently are disclosed. According to one aspect of the present invention, a method for utilizing a memory system that has a non-volatile memory with at least one reserved memory area includes providing power to the memory system, initializing the non-volatile memory, and writing a first signature into the reserved memory area. The first signature is arranged to indicate that the memory system was successfully initialized. In one embodiment, the method also includes executing a power down process on the memory system, and writing a second signature into the reserved memory area which indicates that the power down process has been executed.
