What is Static Random Access Memory (SRAM)?

SRAM, or Static Random Access Memory, is an electronic semiconductor memory that makes use of a bistable latching circuit, commonly referred to as flip-flops to preserve each and every bit of information in the memory. It preserves data bits on the memory circuitry until the power supply is cut off.

Static Random Access Memory is employed in the system where speed or low power are required. Its density is higher than that of dynamic random-access memory. This type of memory configuration is not complex, and it becomes ideal for use with semiconductor memory modules.

Difference between SRAM and DRAM:

Since this memory practices high-capacity storage and is integrated into the embedded system, Static Random Access Memory differs from DRAM (dynamic RAM, which stores bits in cells made up of a capacitor and a transistor) in that it does not require frequent refreshing, whereas dynamic will lose data if not. Static Random Access Memory is also more expensive and speedier than DRAM.

Features and Benefits

  • Access Transistors such as MAL and MAR provide access to preserved data for reading and writing operations.
  • Three operational stages are carried out in memory names hold, read, and write. 
  • Bistable (cross-coupled) INVs for storage.
  • Word line, WL, controls access – WL=0 (hold operation), WL=1 (read/write operation).
  • Reliable chip for long data lifetime.
  • Data is held statically—semiconductor memory is being used to preserve the data, regardless of refreshing the data after each read data operation until the power is cut off to the memory.

What are the applications of SRAM?

They are widely used in various environments with a multitude of devices, such as:

  • Electronics
  • Routers
  • Workstations 
  • LCD screens and printers
  • Microprocessors
  • Computers
