主存儲器(Main memory)，簡稱主存。是計算機硬件的一個重要部件，其作用是存放指令和數(shù)據(jù)，并能由中央處理器(CPU)直接隨機存取?，F(xiàn)代計算機是為了提高性能，又能兼顧合理的造價,往往采用多級存儲體系。即由存儲容量小，存取速度高的高速緩沖存儲器，存儲容量和存取速度適中的主存儲器是必不可少的。主存儲器是按地址存放信息的，存取速度-般與地址無關(guān)。32位(比特)的地址最大能表達4GB的存儲器地址。這對多數(shù)應(yīng)用已經(jīng)足夠，但對于某些特大運算量的應(yīng)用和特大型數(shù)據(jù)庫已顯得不夠，從而對64位結(jié)構(gòu)提出需求。

Main memory, abbreviated as main memory. It is an important component of computer hardware that stores instructions and data, and can be directly accessed randomly by the central processing unit (CPU). Modern computers often use multi-level storage systems to improve performance while also considering reasonable costs. A cache memory with small storage capacity and high access speed, as well as a main memory with moderate storage capacity and access speed, are essential. The main memory stores information by address, and the access speed is generally independent of the address. A 32-bit address can represent up to 4GB of memory address. This is sufficient for most applications, but it is no longer sufficient for some applications with large computational complexity and large databases, thus requiring a 64 bit architecture
