Cache on a STick (COASt)

Definition - What does Cache on a STick (COASt) mean?

Cache on a STick (COASt) is a memory module used to provide additional layers of cache memory on a computer. Implemented in the 1990s, it is a type of external cache that allowed an underlying computer to have an L2 cache.

Techopedia explains Cache on a STick (COASt)

Physically, COASt is a type of fast pipeline-burst static random access memory (SRAM) technology similar to a large single inline memory module (SIMM). It is a mapped cache with a capacity of 256-512 Kb. It also has faster but smaller native random access memory (RAM) modules, which are used for storing cache tags.

COASt is typically installed as a standalone memory component on a card edge low profile (CELP) slot on a computer motherboard. COASt uses data buses to interact with primary cache and other memory modules.
