Abstract

"Associativity" is a highly desirable property of memory devices. Unfortunately, it does not seem to fit very well into the structure of contemporary randomaccess memories. A realization of associativity on such memories is always involved with high density of logic, and in today's technology is bound to be very expensive. Virtually all existing implementations of associative memories are accordingly on a very small scale and are typically used for special purposes such as the support of "virtual memory" schemes. From this situation one can get the impression that large scale associative memories are impractical. Fortunately, however, it turns out that rotating memories, unlike random access memories, are very natural hosts for at least a limited degree of associative addressing.
作为部分联想存储器的旋转存储装置
“结合性”是存储设备非常理想的特性。不幸的是,它似乎不能很好地适应当代随机存取存储器的结构。在这样的存储器上实现联想性总是涉及到高密度的逻辑,在今天的技术中必然是非常昂贵的。实际上,所有现有的关联内存的实现都是在非常小的范围内,并且通常用于特殊目的,例如支持“虚拟内存”方案。从这种情况下,人们可以得到这样的印象:大规模的联想记忆是不切实际的。然而,幸运的是,事实证明,与随机存取存储器不同,旋转存储器是非常自然的宿主,至少是有限程度的关联寻址。
