摘要： A DRAM refresh method, apparatus, and system are provided. A to-be-refreshed area in a refresh block is specified in a refresh instruction, so as to refresh a specified location of a DRAM storage array. The method includes: receiving, by a DRAM refresh apparatus, a refresh instruction from a memory controller, where the refresh instruction includes an identifier of a to-be-refreshed block and refresh information used to indicate a to-be-refreshed area, and the refresh instruction is used to instruct the DRAM refresh apparatus to refresh the to-be-refreshed area in the to-be-refreshed block (S902); generating, by the DRAM refresh apparatus, addresses of to-be-refreshed bank rows in the to-be-refreshed block according to the identifier and the refresh information (S904); and refreshing, by the DRAM refresh apparatus, locations corresponding to the addresses of the bank rows in the to-be-refreshed block (S906). In this way, a DRAM refresh time is shortened, refresh power consumption is reduced, a refresh operation is more flexible, and system resource consumption is reduced while data integrity is ensured.

摘要： Embodiments of the present invention provide a method for reducing power consumption of a memory system and a memory controller. The method for reducing power consumption of a memory system includes: determining whether a dynamic random access memory DRAM memory module with a low access frequency exists in a memory system; when a DRAM memory module with a low access frequency exists, transfer, according to a size of a working set in the memory system, page data that does not belong to the working set to a non-volatile memory NVM memory module, where the page data that does not belong to the working set is page data that does not need to be accessed when a process runs within preset time. According to the embodiments of the present invention, the page data other than the working set is transferred to the NVM memory module, and because the NVM memory module has characteristics of non-volatility and low-power consumption, transferring a part of data in the DRAM memory module to the NVM memory module may reduce the power consumption of the whole memory system.

摘要： Embodiments of the present invention provide a memory system, a memory module, a memory module access method, and a computer system. One or more inter-memory-module interconnection interfaces are added into a memory module, so that a plurality of memory modules in a memory system that separately belong to different memory channels can establish a communication connection through the inter-memory-module interconnection interface, and further, a memory module in the memory system can be accessed by a plurality of memory channels simultaneously. When a load of a certain memory channel is excessively large, accessing a memory module on the memory channel with an excessively large load through another memory channel with a lighter load is implemented, so that a situation that memory channel loads are unbalanced is solved to a certain extent, and a memory channel utilization rate is effectively improved.

摘要： Embodiments of the present invention provide a memory management method and a device, where the method includes: receiving, by a memory manager, a memory access request, where the memory access request carries a virtual address; determining a page fault type of the virtual address if the memory manager finds, in a translation lookaside buffer TLB and a memory, no page table entry corresponding to the virtual address; allocating, by the memory manager, a corresponding page to the virtual address if the page fault type of the virtual address is a blank-page-caused page fault, where the blank-page-caused page fault means that no corresponding page is allocated to the virtual address; and updating, by the memory manager, the page table entry corresponding to the virtual address to the memory and the TLB. By determining the page fault type of the virtual address, the memory manager does not generate a page fault when a blank-page-caused page fault occurs, but allocates a corresponding page to the virtual address. Therefore, the method in the embodiments can reduce a quantity of occurrences of the page fault, thereby improving memory management efficiency.
