Memory management method and system based on heterogeneous hybrid memory

Abstract

The invention provides a memory management method based on a heterogeneous hybrid memory. The method comprises the following steps of: receiving a memory application request; detecting whether a NVM mark exists in the memory application request or not; if the NVM mark exists in the memory application request, judging whether the memory application request accords with a permission request or not, if so, distributing a NVM according to the memory application request, and if not, ending; and, if the NVM mark does not exist in the memory application request, distributing a DRAM according to the memory application request. According to the method disclosed by the invention, whether the NVM mark exists in the memory application request is detected; whether the memory application request accords with the permission request is judged; whether the DRAM or the NVM is distributed is determined according to detection and judgment results; therefore, the NVM and the DRAM can be managed simultaneously; and the invention further provides a memory management system based on the heterogeneous hybrid memory.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a memory management method and system based on heterogeneous hybrid memory. Background technique [0002] With the development of emerging non-volatile random storage medium (Non-Volatile Memory, NVM) technology represented by resistance memory, ferroelectric memory, phase change memory, etc., the development of storage technology has been promoted, and new memory and storage systems The generation of the structure has laid a good foundation. By combining the new NVM and Dynamic Random Access Memory (DRAM), a hybrid memory architecture is built to form a heterogeneous hybrid memory. Heterogeneous hybrid memory has the characteristics of NVM and DRAM at the same time. It not only has the function of conventional memory, but the data stored in DRAM will disappear immediately after power off, which is volatile; at the same time, it can also play the role of NVM after power off. ...

AI Technical Summary

Problems solved by technology

[0005] As a new type of memory, heterogeneous hybrid memory integrates NVM and DRAM. Conventional memory management methods only manage DRAM memory and cannot satisfy the management and operation of NVM memory. Therefore, heterogeneous hybrid memory will not No longer applicable, so it is necessary to provide a memory management method suitable for heterogeneous mixed memory, which can manage NVM memory and DRAM memory at the same time
