Synchronous DRAM (SDRAM) is a type of computer memory that synchronizes its operations with the system clock, allowing for faster data access compared to older memory types. This synchronization enables SDRAM to process multiple commands in a single clock cycle, improving overall performance in computing tasks. SDRAM is commonly used in various devices, including personal computers, servers, and gaming consoles. It has evolved into more advanced forms, such as DDR SDRAM (Double Data Rate SDRAM), which further enhances speed and efficiency by transferring data on both the rising and falling edges of the clock signal.
