High Quality Content by WIKIPEDIA articles! COASt, an acronym for cache on a stick, is a packaging standard for modules containing SRAM used as an L2 cache in a computer. COASt modules look like somewhat over-sized SIMM modules. These modules were somewhat popular in the Apple and PC platforms during early to mid-1990s, but with newer computers cache is built into either the CPU or the motherboard. COASt modules decoupled the motherboard from its cache, allowing varying configurations to be created. A low-cost system could run with no cache, while a more expensive system could come equipped with 512 KB or more cache. Later COASt modules were equipped with pipelined-burst SRAM. The standard was originally defined by Motorola to be between 4.33 and 4.36 inches wide, and between 1.12 and 1.16 inches high. It could be found in many Apple Macintosh in the early-to-mid-90s, but disappeared as the Mac moved to the PowerPC platform. Intel also used the COASt standard for their Pentium systems, where it could be found as late as 1998 in Pentium MMX systems utilizing Intel chipsets such as 430VX and 430TX.
