SRAM (Static Random Access Memory) is a type of semiconductor memory IC within the broader Memory ICs category. It stores digital data in a static storage structure that retains its contents while power is applied, without requiring periodic refresh operations.

SRAM devices provide direct read and write access to memory locations through standard digital control and data interfaces. They are commonly used as volatile memory elements in electronic systems where fast, predictable memory access is required.

• Volatile memory: data is maintained only while powered.
• Static storage: no refresh cycle is needed to preserve stored data during operation.
• Random access: any addressable location can be accessed directly for read or write operations.
