<
storage> (Or
cache block) The smallest unit of memory than
can be transferred between the
main memory and the
cache.
Rather than reading a single word or byte from main memory at
a time, each
cache entry is usually holds a certain number of
words, known as a "
cache line" or "
cache block" and a whole
line is read and cached at once. This takes advantage of the
principle of locality of reference: if one location is read
then nearby locations (particularly following locations) are
likely to be read soon afterward. It can also take advantage
of
page-mode DRAM which allows faster access to
consecutive locations.
