Abstract: A memory access method, apparatus, and system are disclosed. The method can be applied to a system including a local memory device and a remote memory device, where the local memory device comprises local memory and a remote cache. One method includes receiving a memory access request carrying address information of a to-be-accessed memory area. The to-be-accessed memory area indicated by the address information is determined. In response to determining that the to-be-accessed memory area is in the local memory, an access operation is performed on the to-be-accessed memory area according to the memory access request. In response to determining that the to-be-accessed memory area is in the remote memory device and that the remote cache includes a cache block corresponding to the to-be-accessed memory area, an access operation on the cache block according to the memory access request is performed.
