ABSTRACT:
An apparatus and method of flash ROM management. The apparatus comprises a storage device, a strapping component and a process unit. The storage device stores multiple address records comprising an identity and an address range associated with a flash ROM. The strapping component is configured to output a signal to determine flash ROM type. The process unit receives a memory access request with an access range from the CPU and the signal from the strapping component queries the identity by matching the access range and the address range, and finally executes an LPC 1.1 memory access instruction with the identity and the access range corresponding to the memory cycle.
