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.

SRAM

System cache (L1 & L2) uses SRAM.
