US 2019/0196989 A1 · Method, Apparatus, and System for Accessing Memory Device

Abstract

A storage system includes a memory controller and a memory device, and the memory device includes a medium controller, a memory, and a buffer. The medium controller is configured to write, into the buffer after receiving an access request, data requested by the access request. The memory controller is configured to send a query request to the medium controller after sending the access request to the medium controller, where the query request is used to query whether data has been written into the buffer. The medium controller is further configured to determine, based on the query request, whether data has been written into the buffer, and send the data that has been written into the buffer to the memory controller when there is data in the buffer.
