Why is DRAM mostly used rather than SRAM? anybody???

Answer 1

Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically. Because of this refresh requirement, it is a dynamic memory as opposed to SRAM and other static memory.



The advantage of DRAM is its structural simplicity: only one transistor and a capacitor are required per bit, compared to six transistors in SRAM. This allows DRAM to reach very high density. Like SRAM, it is in the class of volatile memory devices, since it loses its data when the power supply is removed. Unlike SRAM however, data may still be recovered for a short time after power-off.

Answer 2

S ram is used less often due to it's size limitations and speed.



DRAM is faster, offers more space and is a much better choice. All RAM in modern computers today is DRAM. SRAM was phased out a while back.



Hope that helps.

Answer 3

In short, Dram is cheaper than Sram.

Sram is technically faster, and uses less power when not running at high speeds, but costs more to produce, and thats all that matters to the manufacturers.
