Abstract
A control method of a memory device, a memory device and a memory system are provided. The memory system includes a memory control unit and a memory die. The memory die performs a data access operation asynchronously with respect to a system clock according to address information and an access signal generated from the memory control unit. When operating in a read mode, the memory die generates a data tracking signal according to a memory internal read time which is an elapsed time for data to be read to be read out from the memory die. The memory control unit and the memory die obtain required data according to respective data tracking signals transmitted therebetween. The control method defines an asynchronous memory interface protocol which realizes reliable and high speed data transmission.
