Abstract: Apparatuses and methods for a cache memory are described. In an example method, a transaction history associated with a cache block is referenced, and requested information is read from memory. Additional information is read from memory based on the transaction history, wherein the requested information and the additional information are read together from memory. The requested information is cached in a segment of a cache line of the cache block and the additional information in cached another segment of the cache line. In another example, the transaction history is also updated to reflect the caching of the requested information and the additional information. In another example, read masks associated with the cache tag are referenced for the transaction history, the read masks identifying segments of a cache line previously accessed.

Abstract translation: 描述用于高速缓冲存储器的装置和方法。 在示例性方法中，引用与高速缓存块相关联的事务历史，并且从存储器读取所请求的信息。 基于事务历史从存储器读取附加信息，其中从存储器一起读取所请求的信息和附加信息。 请求的信息被缓存在高速缓存块的高速缓存行的段中，并且缓存在高速缓存行的另一段中的附加信息。 在另一个示例中，交易历史也被更新以反映所请求信息和附加信息的缓存。 在另一示例中，对于事务历史引用与高速缓存标签相关联的读取掩码，读取掩码标识先前访问的高速缓存行的段。
