Difference Between SRAM And DRAM

Difference Between SRAM And DRAM: RAM stands for Random Access Memory, which is computer memory and is accessible by the CPU. RAM contains temporary data, and when the power to the laptop/desktop is off, the data and the information also disappear.

In broader terms, the data which can be modified easily are usually stored in RAM. With this, there are two types of RAM i.e. Static Random Access Memory (SRAM) and Dynamic Random Access Memory (DRAM).

Furthermore, the significant difference between SRAM and DRAM is that SRAM is faster, more expensive, and more energy-saving than DRAM. However, DRAM is a type of memory chip that can store more data than SRAM but it usually uses more power.

In this blog, we have shared complete details on SRAM, DRAM, and the major difference between SRAM and DRAM below.

What is SRAM?

The SRAM full form is Static Random Access Memory. SRAM is a kind of random-access memory that saves each bit using latching circuitry. It also loses all the temporary data as soon as the electricity stops.

Thus, it is essential to update SRAM regularly. It is faster and more costly than DRAM. With this, the data is in transistors and requires a steady supply of power.

Furthermore, SRAM is static as it stores the data without any updates because of the regular power. With this, the usage of SRAM is in cache memories.

What is DRAM?

The DRAM full form is Dynamic Random Access Memory. It is a type of RAM that enables each bit of data to be saved in its own capacitor in the integrated circuit.

Furthermore, DRAM is dynamic as it needs regular updates and changes or actions, such as refreshing, to retain the data. It is used in the main memory. With this, capacitors and some transistors play an important role in creating DRAM. It is slow and less costly than SRAM.
