SRAM, or Static Random-Access Memory, is a specific type of RAM known for its speed and stability. Here's a breakdown of its key characteristics:
- A high-performance memory chip that retains data as long as it has power, unlike regular RAM (DRAM) that needs constant refreshing.
- Made up of latching circuits which hold data using transistors instead of capacitors like DRAM.
- Typically used in smaller capacities for critical applications where speed and reliability are paramount.

Key features:
- Faster access times: Compared to DRAM, SRAM boasts significantly faster read and write speeds, making it ideal for applications requiring quick data retrieval, like CPU caches and embedded systems.
- Lower power consumption when idle: While active, SRAM consumes more power than DRAM. However, in idle states, it uses significantly less, making it suitable for battery-powered devices where efficiency is crucial.
- Simpler design: The latching circuit design of SRAM is less complex compared to DRAM's refresh circuitry, contributing to its faster operation and potentially lower cost for smaller capacities.
- Non-volatile (within limits): While technically classified as volatile memory, SRAM can exhibit data remanence for a short period even after power loss, depending on factors like temperature and manufacturing process. This can be advantageous in certain situations.
