A memory cache, sometmes called a <i>cache store</i>
or <i>RAM cache</i>, is a porton of memory made of
high-speed statc RAM (SRAM) instead of the
slower and cheaper dynamic RAM (DRAM) used
for main memory. Memory caching is effectve
because most programs access the same data or
instructons over and over. By keeping as much
of this informaton as possible in SRAM, the
