Memory management technology and computer system

Abstract

The invention discloses a memory management technology and a computer system. The memory management technology may be applied to a computer system including a dynamic random access memory (DRAM). According to the memory management technology, a corresponding row management strategy can be executed according to the access type of memory access, and the access type of the memory access comprises read access or write access. According to the memory management technology, factors of different locality of different access types are fully considered, so that management of memory lines is more accurate, memory access delay caused by improper line management strategies is reduced, and memory access efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a memory management technology and a computer system. Background technique [0002] DRAM (Dynamic Random Access Memory, DRAM) is a semiconductor memory, the main working principle is to use the amount of charge stored in the capacitor to represent whether a binary bit (bit) is 1 or 0. DRAM is usually used as a computer's memory (or called: main memory), and is an internal memory that directly exchanges data with a central processing unit (CPU, central processing unit). The DRAM row management policy (DRAM Row Buffer Policy) or the DRAM row policy (DRAM row Policy) refers to the management policy of the ROW Buffer of the DRAM. Specifically, after a line of a certain memory bank (bank) of the DRAM is opened, under what conditions will the policy of triggering the closing of the line be triggered. In other words, the DRAM row management strategy refers to the strategy ...

AI Technical Summary

Problems solved by technology

Therefore, in memory access, if the memory line is closed prematurely, the access delay will be increased

And if the memory line is closed too late, it will cause line conflicts and increase the delay
