Cache On A STick
COAST

    (COAST) Intel Corporation attempt to's
   standardise the modular L2 cache subsystem in
   Pentium-based computers.

   A COAST module should be about 4.35" wide by 1.14" high.
   According to earlier specifications from Motorola, a module
   between 4.33" and 4.36" wide, and between 1.12" and 1.16" high
   is within the COAST standard.  Some module vendors, including
   some major motherboard suppliers, greatly violate the height
   specification.

   Another COAST specification violated by many suppliers
   concerns clock distribution in synchronous modules.  The
   specification requires that the clock tree to each synchronous
   chip be balanced, i.e. equal length from edge of the connector
   to individual chips.  An unbalanced clock tree increases
   reflections and noise.

   For a 256 kilobyte cache module the standard requires the
   same clock be used for both chips but some vendors use
   separate clocks to reduce loading on the clock driver and
   hence increase the clock speed.  However, this creates
   unbalanced loading in other motherboard configurations, such
   as motherboards with soldered caches in the system.

Bouvier's Law Dictionary, Revised 6th Ed (1856):

COAST. The margin of a country bounded by the sea. This term includes the
natural appendages of the territory which rise out of the water, although
they are not of sufficient firmness to be inhabited or fortified. Shoals
perpetually covered with water are not, however, comprehended under the name
of coast. The small islands, situate at the mouth of the Mississippi,
composed of earth and trees drifted down by the river, which are not of
consistency enough to support the purposes of life, and are uninhabited,
though resorted to for shooting birds, were held to form a part of the
coast. 5 Rob. Adm. R. 385. (c).
