MEMORY SYSTEM AND METHOD FOR MANAGING CACHE MEMORY

A memory system and a method for managing a cache memory are disclosed. The memory system includes: at least one high bandwidth memory device configured to store data or output stored data according to an access command; a processor configured to generate an access command for the high bandwidth memory device; and a logic die on the high bandwidth memory device and including a last level cache that provides cache functionality to the processor. The last level cache is configured to, in response to a cache read request or a cache write request by the processor, perform a cache bypass operation to directly access the high bandwidth memory device without a cache replacement operation when an invalid line and a clean line do not exist in a cache miss state. 公开了一种存储器系统和用于管理高速缓存存储器的方法。所述存储器系统包括：至少一个高带宽存储器装置，被配置为根据访问命令存储数据或输出存储的数据；处理器，被配置为生成用于高带宽存储器装置的访问命令；以及逻辑裸片，在高带宽存储器装置上并且包括末级高速缓存，末级高速缓存将高速缓存功能提供给处理器。末级高速缓存被配置为：响应于通过处理器的高速缓存读取请求或高速缓存写入请求，当无效行和干净行在高速缓存未命中状态下不存在时，执行高速缓存旁路操作以直接访问高带宽存储器装置而无需高速缓存替换操作。
