Question

Different Betweens in SRAM and DRAM !

Answer 1

Answer:

Explanation:

Application Differences:

SRAM

SRAM stands for Static Random Access Memory  DRAM stands for Dynamic Random Access Memory

Faster access is due to the usage of transistors to store single bit of data  

SRAMs are used for cache memories due to faster access time  

DRAM

DRAM stands for Dynamic Random Access Memory

DRAMs are used for main memories due to comparatively slower access time.

DRAMs use capacitor to store bits where each capacitor holds a single bit

Parameter differences  

Speed: SRAMs are faster due to presence of transistors. DRAMs are slower due to presence of capacitors

Size: Due to complexity involved in the internal circuits, SRAMs are smaller in capacity for same size of the chip. DRAMs are larger as compared to SRAMs since their capacity for a given physical size is more.

Cost: SRAMs are costlier and the per bit storage cost is more than that of the DRAMs. DRAMs are cheaper and the per bit storage cost is less than that of the SRAMs

Answer 2

SRAM :

• SRAM has lower access time, so it is faster compared to DRAM.
• SRAM is costlier then DRAM.
• SRAM requires constant power supply, which means this type of memory consumes more power.
• Due to complex internal circuitry, less storage capacity is available compare to the same physical size of DRAM memory chip.
• SRAM has low packaging density.

DRAM :

• DRAM has higher access time, so it is lower than SRAM.
• DRAM costs less compair to the SRAM.
• DRAM offers reduced power consumption, due to the fact that the information is stored in capacitor.
• Due to the small internal circuitry in the one-bit memory cell of DRAM, the large storage capacity is available.
• DRAM has high packaging density.
