Embodiment Construction

[0014] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that electronic device manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The "comprising" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means. .

[0015] The concept of the present invention is ...

Abstract

A storage system (200) includes a data storage device (112) having a plurality of data storage lines (113), a tag storage device (114) having a plurality of address tags (115, 116) each associated with one data storage line (113) allocated in the data storage device (112), and a controller (117). The controller (117) sets a first number of address tags (115, 116) and configures a first number of data storage lines (113) to serve as a first data storage line with a first data storage line size, and sets a second number of address tags (115, 116) and configures a second number of data storage lines (113) to serve as a second data storage line with a second data storage line size. The second data storage line size is different from the first data storage line size.

Description

technical field [0001] The present invention relates to accessing buffered data (e.g., cache data), and more particularly to memory systems having data storage lines (e.g., cache lines) of different data storage line sizes (e.g., different cache line sizes) . Background technique [0002] A cache memory (cache memory) is a high-speed buffer used to temporarily store part of a large-capacity and slow-speed memory (eg, main memory) for repeated access. Most existing caches consist of a set of entries. Each entry consists of a data block (or data line) and an address tag; the address tag is associated with the location of the data in the larger main memory. A cache is access-associative - the key to a cache is not the location in the cache, but the location in main memory. To speed up storage, caches may not be fully associative, but may be set associative, direct mapped, or hashed. Most caches include multiple cache lines, each having a fixed cache line size. In slightly ...
