关联或内容寻址存储器中的数据是通过其值的属性来查找的，而不是像传统存储器那样通过其地址来查找。这样的属性可以是存储的一个字或一组字的开头处的位的模式，例如，其用作标识标签。关联存储器用于多级存储器系统（参见存储器层次），其中一个小的快速存储器（如高速缓存）可以保存较大存储器的某些块的副本，以便快速访问。
Data in an associative or content-addressable memory is looked up by properties of its value, rather than by its address as in conventional memory. Such a property might be a pattern of bits at the start of a word or set of words of storage, for example, that serves as an identifying tag. Associative memory is used in multilevel memory systems (see MEMORY HIERARCHY), in which a small fast memory such as a cache may hold copies of some blocks of a larger memory for rapid access.
