Patent ID: 7441138

Claim:
A data system capable of controlling multiple data access comprising: a storage device for receiving a control signal and an address signal and for accessing data stored at an address corresponding to the address signal; a multiple access control device for receiving a plurality of request commands given by a plurality of hosts when attempting to access the storage device, and thereby generating corresponding phase control signals and access signals based on the request commands; a timing signal generating device for receiving the phase control signals generated by the multiple access control device and thereby generating a plurality of timing signals each related to a corresponding request command and including a plurality of enabling time slots based on a phase reference signal and a corresponding phase control signal, wherein only a timing signal among the plurality of timing signals includes an enabling time slot at a certain point of time; an access control device for receiving the access signals and the timing signals respectively generated by the multiple access control device and the timing signal generating device, and outputting corresponding control signals to the storage device during the enabling time slots of corresponding timing signals; and an address control device for receiving the access signals and the timing signals respectively generated by the multiple access control device and the timing signal generating device, and generating a plurality of address signals each related to a corresponding access signal.
