Overview
SRAM is a type of volatile memory that does not need to be periodically refreshed, unlike DRAM. This makes it significantly faster but also more complex and expensive to manufacture.
Key Characteristics
- Speed: Offers very low latency and high access speeds.
- Complexity: Requires more transistors per bit of storage compared to DRAM.
- Power Consumption: Uses more power when active but very little when idle.
Primary Use
SRAM is primarily used for CPU cache (L1, L2, L3) where speed is the most critical factor.
