Static RAM (SRAM), in computer science, a form of
semiconductor memory (RAM). Static RAM storage is based on
the logic circuit known as a flip-flop, which retains the
information stored in it as long as there is enough power
to run the device. A static RAM chip can store only about
one-fourth as much data as a dynamic RAM chip of the same
complexity, but static RAM does not require refreshing and
is usually much faster than dynamic RAM. It is also more
expensive. Static RAMs are usually reserved for use in
caches.
Dynamic RAM (DRAM) in computer science, a form of
semiconductor random access memory (RAM). Dynamic RAMs
store information in integrated circuits that contain
capacitors. Because capacitors lose their charge over time,
dynamic RAM boards must include logic to “refresh”
(recharge) the RAM chips continuously. While a dynamic RAM
is being refreshed, it cannot be read by the processor; if
the processor must read the RAM while it is being
refreshed, one or more wait states occur. Because their
internal circuitry is simple, dynamic RAMs are more
commonly used than static RAMs, even though they are
slower. A dynamic RAM can hold approximately four times as
much data as a static RAM chip of the same complexity.
