Serial Advanced Technology Attachment (SATA) interface system used for computer system has memory module used as buffer or cache memory between SATA devices and south-bridge chip, or as virtual disk capable of fast access to data

摘要

The SATA interface system has a memory module (140) used as a buffer or cache memory between SATA devices (160) and a south-bridge chip (100), or as virtual disk capable of fast access to data. A control module (150) determines the storage destination of the received data based on the degree of occupancy of a CPU, and the data transmission speed of a SATA device. An independent claim is included for a SATA interface method.
