Differences between DRAM and SRAM?..

Answer / coolmoon

SRAM (Static RAM)
Data is stored in cross-coupled inverters
Large cell - requires several transistors (6T cell standard)
Fast access time / Low density
Integrates easily into logic fab processes

DRAM (Dynamic RAM)
Data is stored in form of charged capacitors
Small cell - requires one capacitor and one transistor
“Refresh” operation required every few milliseconds
Slower access time but much higher density than SRAM

Differences between DRAM and SRAM?..

Answer / balaji

dram consist of only one transistor and then it is a
volatile memory.it is refreshed periodically otherswise
stored informations are deleted.
sram consists of five or six transistors and it is also a
volatile memory, if power is shutoff or rewrite the data
means already stored informations are deleted.it reqiures
power continuously.

Differences between DRAM and SRAM?..

Answer / prachee

SRAM
>Short for static random access memory, and pronounced ess-
ram.
>SRAM is a type of memory that is faster and more reliable
than the more common DRAM
>SRAM's store bits (1's or 0's) in memory cells that are
basically flip flops.To store 1 bit of information about 6
transistors are used
>it does not required refreshing
>it is more costlier than DRAM in terms of cost per bit,

DRAM
>DRAM stands for dynamic random access memory, a type of
memory used in most personal computers

>In DRAM to store 1 bit of information 1 transistor and 1
capacitor is used.
>The information is stored in the capacitor in form of
charge, so it required refreshing to retain the charge or
data in the capacitor.

Differences between DRAM and SRAM?..

Answer / richa

sram:
*faster
*expensive
*used as cache
*more power consumption
*uses internal flip flop to store binary information.

dram:
*slower
*cheaper
*used as main memory
*less power consumption
*used to store binary info. in the form of electric charges
that are applied to capacitors.

Differences between DRAM and SRAM?..

Answer / anna dee

static RAM
1. need not refreshing
2. Use Flip-Flop (Flip-flop will not lose power)
3. Expensive
4. Can not be compress so much

Dynamic RAM
1. Need Refreshing
2. USe Capacitor (capacitor hold current and will lose it)
3. Cheaper
4. Can be Compress

Differences between DRAM and SRAM?..

Answer / anuj gupta

1.SRAM will maintain its data as long as power is provided
to memory chips.it does not require to be rewrite frequently.
2*.the SRAM consists essentially of internal flip flops that
store the binary information
3.SRAM is faster than DRAM
4. SRAM is often used as cache memory due to its speed

1.DRAM is called dynamic because it must constantly be
refreshed we can said that it will lose the data which we
supposed to be storing.
2*.the DRAM stores the information in the form of electric
charges that are applied to capacitors

3.DRAM chips requires only 1 transistor and a capacitor per bit.

Differences between DRAM and SRAM?..

Answer / vimalanathan j

SRAM stands for Static Random Access Memory. In this to
store either 1 or 0 (i.e.) a single bit 6 transistors are
required. SRAM is the volatile memory. They can retain the
data until the system is powered off. As they use 6
transistor per bit they have faster access time and they
don't require to be periodically refreshed.

DRAM stands for Dynamic Random Access Memory. In this to
store a bit it requires 1 transistor and 1 capacitor.As
they use capacitor it requires to periodically refreshed.
This reduces the overall performance. But when compared the
size of SRAM and DRAM, SRAM is bigger than DRAM and on
costwise DRAM is economical

Differences between DRAM and SRAM?..

Answer / syed murtaza

DRAM stands for dynamic Random Access Memory. In DRAM, individual cells are made by using capacitors. This type of memory is used in most of the computers. In order to maintain data in DRAM chip, it must be refreshed with electric charge frequently (or periodically). Otherwise data stored in DRAM my be lost. During refreshing process, CPU has to wait for writing and reading data to and from the DRAM. Therefor it is slow memory.
SRAM.
SRAM stants for Static Random Access memory. In SRAM, indidual cells are made by using digital gates. Each cell can hold its value without any need to refresh it frequently. It is faster than DRAM; because it does not have to be refreshed with electric charge frequently. CPU does not have to wit to access data from SRAM. The SRAM chips utilize less power. The SRAM chip is more expensive than the DRAM chip.
In most modern computer SRAM technology is used to build very fast memory. This memory is known as the cache memory.

Differences between DRAM and SRAM?..

Answer / rajan

SRAM (Static RAM)
*stores data till the power is switched off
Uses a set of transistors for each memory cell

*Does not refresh the memory cell after each
reading of the transistors.

DRAM (Dynamic RAM)
*stores data only for few milliseconds
Uses a single transistor and capacitor
for each memory cell

*Needs to refresh the memory cell after each
reading of the capacitor.
