Abstract
A memory access method for accessing data from a non-volatile memory in a south bridge is provided. Memory access is performed under a system management mode (SMM). Under the protection of the SMM mode, the desired memory address is not altered by an interrupt handler, therefore memory data is accessed correctly.
