Difference between static and dynamic RAM?..

Answer / monika parmar

static ram:it consist of internal flip-flops that store
binary information.The stored information remains as long as
the power is applied to the unit.It is easy to used & has
shorter read and write cycles.
dynamic ram:it stores the binary information in the form of
electric charge applied to capacitor.The capacitor is
present inside the MOS tansistors.The storage charge on the
capacitor tends to be discharged with time & the capacitor
must periodically charged by refreshing dynamic memory.

Answer / rohan nimbalkar

Dynamic RAM

The most common form of RAM in a computer is dynamic RAM.
Each chip contains millions of tiny memory cells made up of
a transistor and a capacitor, and can contain one bit of
information – a 0 or a 1. In order to store a bit of
information, the computer needs to put a tiny amount of
power into the cell to charge the capacitor, but this energy
leaks out quickly. So to keep information in dynamic RAM,
your computer needs to recharge all the cells in the memory
chip every few milliseconds, or all the data is lost. This
constant refreshing gives dynamic RAM its name.

Static RAM
On the other hand, works with a completely different
technology. Each cell holds a bit of information that can be
flip-flopped, from 0 to 1, and doesn’t need to be refreshed;
although, it requires more transistors to make it work.
Because it never needs to be refreshed, it uses less power
and operates much more quickly. But it’s much more expensive
to manufacture.
All modern computers use a tiny amount of static RAM, as a
cache close to the CPU where it’s most needed to help
perform calculations quickly, and then larger quantities of
dynamic RAM to hold programs and data.

Answer / deepak bhatt

# SRAM (static RAM). This type of memory maintains data in
storage as long as it is powered. Because it is faster and
more reliable and expensive than DRAM, SRAM is most often
used as cache memory. Earlier forms of SRAM were classified
as Async or Sync RAM if they were synchronized with the
system clock. The most common type of SRAM today is pipeline
burst SRAM, which can operate at higher bus speeds.

# DRAM (dynamic RAM). This type of RAM retains its data by
being continuously rewritten every few milliseconds. Like
SRAM, the data in storage is volatile, meaning it is lost
when the system is not powered. DRAM is the most common type
of expandable company memory in workstations and servers
today, but there are several different types of DRAM.

Answer / saikumar

dynamic ram does not need the way to which the data is
recieve or submit
while in static ram it is need to show the path to which
the data is recieve or submit

Difference between static and dynamic RAM?..

Answer / zaheer

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.

Difference between static and dynamic RAM?..

Answer / vinay

Static RAM: No refreshing, 6 to 8 MOS transistors are
required to form one memory cell, Information stored as
voltage level in a flip flop.
Dynamic RAM: Refreshed periodically, 3 to 4 transistors are
required to form one memory cell, Information is stored as
a charge in the gate to substrate capacitance.

Difference between static and dynamic RAM?
Dynamic RAM:-Dram stores the data in the form of charge
into capacitor.for storing another charge capacitor require
to refresh the data which it holds.This refresh operation
is where dynamic RAM gets its name.

Static RAM:-is a type of semiconductor memory where the
word static indicates that, unlike dynamic RAM (DRAM), it
does not need to be periodically refreshed, as SRAM uses
bistable latching circuitry to store each bit.

Difference between static and dynamic RAM?..

Answer / dinkar v

static ram:5 to 8 MOS transistors are used to form a memory cell,it requires no refreshing,information is stored as voltage level in flip flop compared to dynamic where data is stored as charge and refresh is requred.used in cache memory low speed compared to dynamic and more cost.

Answer / nirvair jatt

Answer
# 7
STATIC RAM vs DYNAMIC RAM
Firstly we anxious with static RAM
1)it does not loose signal strength.
2)no refreshing.
3)They made of transistors.

Where as Dynamic RAM
1)looses its signal 1 becomes 0
2)periodic refreshing of memory is needed.
3)These are mostly made of capacitors.
