Static RAM (SRAM)
Of the two basic types
of RAM, SRAM is the faster of the two.
This is due in part to the way SRAM is made.
SRAM is made up of tiny transistors that
store all of the 1's and 0's in the memory.
As you learned in Chapter 0001, you can think of transistors
as light switches that are either on (1)
or off (0). Being that SRAM is made of these
tiny light switches (transistors), it does
not require that the system refresh the
contents of the memory frequently. Once the transistor's
position is set to either on or off, it
will always maintain that position as long
as there is power supplied to the system.
The drawback to this technology
is that it is more expensive to produce than Dynamic
RAM, and it takes up significantly more space
than DRAM. An SRAM module is often four
times larger in physical size than a DRAM
module of the same capacity. Therefore, SRAM
is often used for system cache that does
not need to have a large capacity, yet needs
to be very fast to aid in system
performance.

System cache (L1 & L2) uses SRAM.
