Method and apparatus for determining the write delay time of a memory utilizing the north bridge chipset as in charge of the works for checking the write delay time of the memory

摘要

A method and apparatus for determining the write delay time of a memory are provided. The apparatus includes a CPU, a memory, a north bridge chipset, a south bridge and a BIOS. The north bridge chipset, which is connected to the CPU and the memory, writes a pattern to the memory according to different write delay times. The BIOS reads the pattern stored in the memory, and checks the correctness of the read pattern to determine the common write delay time.
