Abstract: A memory management unit includes a TLB configured to cache PTEs including a mapping between a virtual and a physical frame number, and to convert a virtual address into a physical address using the cached PTEs. A page table walk request queue is configured to queue page requests corresponding to a virtual page number when a TLB miss is occurred, and one or more PTWs are configured to acquire a PTE from the main memory, and to convert the virtual page numbers into physical frame numbers using the PTE. A PTW is configured to select associated page table walk requests having the same base address of corresponding virtual page numbers, to consecutively provide cache line requests for acquiring PTEs corresponding to the associated page table walk requests, to acquire the PTEs corresponding to the associated PTE requests, and to provide the acquired PTEs to the TLB.

Abstract: A memory device is configured to communicate with a plurality of host devices, through an interconnect, and includes a memory including a plurality of memory regions that includes a first memory region that is assigned to a first host device and a second memory region that is assigned to a second host device. The memory device further includes a direct memory access (DMA) engine configured to, based on a request from the first host device, the request including a copy command to copy data that is stored in the first memory region to the second memory region, read the stored data from the first memory region, and write the read data to the second memory region without outputting the read data to the interconnect.

Abstract: A memory device includes; a first memory of first type, a second memory of second type different from the first type, and a memory controller. The memory controller receives an access request and workload information related to work of an external processor, processes the access request using the workload information, and accesses at least one of the first memory and the second memory in response to the access request.
