Abstract

The invention discloses a method and a device for managing a heterogeneous hybrid memory. The heterogeneous hybrid memory comprises an NVM (Non-Volatile Memory) and a DRAM (Dynamic Random Access Memory). The method comprises the following steps: receiving a memory allocation request sent by a user process, and judging the user process; if the user process is a system-level process, allocating the memory space of the DRAM to the user space; if the user process is a batch processing process, allocating the memory space of the NVM to the user process. By virtue of the memory management mechanism, the system-level process is capable of performing data processing in the DRAM with relatively high access rate, the batch processing process is capable of performing data processing in the NVM, so that influence of the access speed difference between the DRAM and the NVM on the data processing speed is reduced, and the data processing speed of the user process and the overall processing performance of the system are enhanced.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for managing heterogeneous mixed memory. Background technique [0002] With the advent of the cloud era, big data (Big data) has also attracted more and more attention. The in-memory computing spawned by big data has put forward extremely high demands on the speed, capacity, energy consumption and reliability of computer memory. The traditional computer memory is composed of DRAM (Dynamic Random Access Memory, Dynamic Random Access Memory). Since the medium size of DRAM has reached the limit of the CMOS (Complementary Metal-Oxide-Semiconductor, Complementary Metal-Oxide-Semiconductor) process, therefore, DRAM faces great challenges in terms of system stability, data reliability and lifespan. [0003] The emergence of NVM (Non-Volatile Memory, non-volatile memory) provides a new way to expand computer memory, and at the same time promotes the evolution of co...
