Computer system of heterogeneous hybrid memory architecture, control method of computer system and memory detection system

Abstract

The invention relates to a computer system of heterogeneous hybrid memory architecture. The computer system comprises a memory unit, a non-volatile memory unit and a basic input and output system BIOS unit, wherein the memory unit comprises a first serial presence detect SPD chip and accesses the computer system through a dual inline memory module DIMM interface, and the first SPD chip comprises memory capacity information of the memory unit; the non-volatile memory unit comprises a second SPD chip and accesses the computer system through a DIMM interface, and the second SPD chip comprises memory capacity and memory type information of the non-volatile memory unit; the BIOS unit is used for acquiring capacity information of the second SPD chip at a power on self-test POST stage and then forming a system memory report by the capacity information of the second SPD chip and the memory capacity information of the memory unit. The invention further relates to a control method for the computer system and a memory detection system in the computer system. According to the computer system, the control method and the memory detection system, the whole computer system obtains a certain degree of balance on reading and writing speed and costs.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a computer system with heterogeneous hybrid memory architecture, a computer system control method and a memory detection system. Background technique [0002] In view of the characteristics of cloud computing and big data, such as fast incremental speed and low time locality, the traditional computing-centric model is faced with limited memory capacity, high input / output pressure, low cache hit rate, and data processing challenges. There are many challenges such as low overall performance, and it is difficult to achieve the best balance between performance, energy consumption and cost, which makes the current computer system unable to handle big data above PB level. With the development of emerging non-volatile memory (Non-VolatileMemory, NVM) technology represented by resistive memory, ferroelectric memory, phase change memory, etc., the boundary between traditional me...

AI Technical Summary

Problems solved by technology

[0006] The traditional architecture determines that NVM is only used as an external storage device. During the computer startup process, the BIOS will not form a unified system memory report for NVM and DRAM, and NVM cannot be used as memory.
