What is the major difference between SRAM and DRAM?

The major difference between SRAM and DRAM is that SRAM is a type of on-chip memory with a short access time, whereas DRAM is an off-chip memory with a long access time. As a result, SRAM outperforms DRAM.

SRAM, or static random access memory, is used as cache memory. It makes data more accessible to the computer so it can utilize it more rapidly, but it is not accessible to the end user.

DRAM, or dynamic random access memory, is the physical memory that allows the computer to run applications and other programs. For example- when you see in a PC/ laptop description that it has 8GB of RAM, it refers to DRAM.

What is the speed difference between SRAM and DRAM?

The speed difference between SRAM and DRAM is provided below.SRAM is used as on-chip memory. It takes less time to access data than DRAM. As a result, it is quicker in comparison. DRAM has properties similar to off-chip memory. Because the considerable access time is longer than SRAM, it is slower.

What is the difference between SRAM and DRAM in terms of storage?

In terms of storage, the difference between SRAM and DRAM is that SRAM often has a reduced storage capacity. However, DRAM has a greater storage capacity than SRAM.

Difference between SRAM and DRAM: When the power to the PC or laptop is turned off, the information saved in the Random Access Memory (RAM) is gone. The BIOS may be used to examine the information saved in RAM. It is also known as the computer system's primary memory, temporary memory, cache memory, or volatile memory. Following are the two types of RAM:

SRAM
DRAM

SRAM is a type of memory chip that is both quicker and more energy-efficient than DRAM. However, DRAM is a type of memory chip that can store more data than SRAM but consumes more power. Here, we will discuss in detail SRAM, DRAM, and the difference between SRAM and DRAM in the sections provided below.

What is SRAM?

SRAM stands for static random-access memory. SRAM is a form of random-access memory (RAM) that stores each bit using latching circuitry (flip-flops). It is a volatile memory, which means that data is lost when the power is turned off.

SRAM must be updated on a regular basis. It is quicker and more costly than DRAM, and it is often used for a CPU's cache and internal registers. Transistors retain data and require a steady power supply. SRAM does not need to be updated to recall the data it stores because of the constant power. SRAM is named static because it does not require any changes or actions, such as refreshing, to keep the data intact. It's a type of memory that's employed in caches.

What is DRAM?

DRAM stands for dynamic random-access memory. It is a form of RAM that allows each bit of data to be stored in its own capacitor within an integrated circuit. It is a kind of computer memory that may be found in any current desktop computer.

DRAM is named dynamic because it requires regular modification or activity, such as refreshing, to keep the data intact. It is employed in the implementation of main memory. Capacitors and a few transistors are used to make DRAM. The capacitor is used to store data in this form of RAM, with a bit value of 1 indicating that the capacitor is charged and a bit value of 0 indicates that the capacitor is discharged.

What is the Difference Between SRAM and DRAM?

As we have read about static random access memory (SRAM) and dynamic random access memory (DRAM) in the sections above. Now, let us discuss the difference between SRAM and DRAM provided in the table below.

SRAM	DRAM
It can store data as long as electricity is available.	It saves data for as long as the power is on or for a few moments if the power is turned off.
Because capacitors aren't utilized, there's no need to refresh.	The contents of the capacitor must be updated on a regular basis in order to store information for a longer amount of time.
SRAM has a storage capacity of 1 MB to 16 MB in most cases.	DRAM, which is often found in tablets and smartphones, has a capacity of 1 GB to 2 GB.
The storage capacity of SRAM is low.	The storage capacity of DRAM is higher than SRAM.
SRAM is more expensive than DRAM.	DRAM is less expensive than SRAM.
It is comparatively faster.	It is comparatively slower.
The power consumption is minimal, and the access speed is quick.	The cost of production is low, and the memory capacity is higher.
SRAM is used in cache memories.	DRAM is used in main memories.
