DRAM is made with cells that store data as charge on capacitors. The presence or absence of charge on a capacitor is interpreted as a binary 1 or 0. Because capacitors have a natural tendency to discharge, dynamic RAMs require periodic charge refreshing to maintain data storage. The term dynamic refers to this tendency of the stored chrage to leak away, even with power continuously applied.

SRAM is a digital device, using the same logic elements used in the processor. In a SRAM, binary values are stored using traditional flip-flop logic-gate configurations. A static RAM will hold its data as long as power is supplied to it.

What is the difference between DRAM and SRAM in terms of characterstics such as size?

•Dynamic cell (DRAM) -Simpler to build, smaller -More dense -Less expensive -Needs refresh -Larger memory units •Static (SRAM) -Faster -Cache


Why sram less dense than dram?

SRAM is less dense than DRAM because SRAM cells are made up of multiple transistors, typically 6 transistors per cell, which require more space compared to the single transistor used in DRAM cells. This extra space needed for each cell in SRAM makes it less dense in terms of storing data compared to DRAM.

What is the Difference of sram and dram in term of application?

both are semiconductor memory. semiconductor means that both need continuous voltage or charge to sustain their data. SRAM used for cache , and store data in the flip flop, no need for refreshing , fast access but more expensive. DRAM used for main memory , and store data in capacitor, need for refreshing , slow access but less expensive.

What advantage does DRAM have over SRAM?

Dynamic Random Access Memory contents need to be continuously refreshed. When its contents are being refreshed, memory can not be read from nor write to. Another point to note is that DRAM is cheap to manufacture (This could be the only advantage it has to SRAM).Where as in Static Random Access Memory, memory need not to be continuosly refreshed and therefore memory can be accessed at any time. SRAM is expensive to manufacture.

How would you write about SRAM?

---SRAM--- Static random access memory (SRAM) is a type of semiconductor memory where the word static indicates that it, unlike dynamic RAM (DRAM), does not need to be periodically refreshed, as SRAM uses bistable latching circuitry to store each bit. SRAM exhibits data remanence, but is still volatile in the conventional sense that data is eventually lost when the memory is not powered. The term SDRAM, which stands for synchronous DRAM, should not be confused with SRAM.
