Title: METHOD, APPARATUS, AND SYSTEM FOR ACCESSING MEMORY DEVICE
Abstract:
Embodiments of the present invention provide a method, apparatus, and system for accessing a memory device. The present invention implements asynchronous access to a memory device. The system comprises a memory controller and a memory device. The memory device comprises a medium controller, a memory, and a buffer. The medium controller is used for writing, into the buffer according to each access request received from the memory controller, data that is stored in the memory and requested by each access request. The memory controller is used for sending a query request to the medium controller after sending at least one access request to the medium controller, wherein the query request is used for querying whether there is data written into the buffer. The medium controller is further used for determining, according to the query request, whether there is data written into the buffer, and if it is determined that there is data written into the buffer, sending the data written into the buffer to the memory controller.
