SDRAM, or Synchronous Dynamic Random Access Memory, is a type of computer memory that is synchronized with the system bus, allowing for faster data transfer rates compared to earlier types of random-access memory (RAM)
. The operation of SDRAM is coordinated by an externally supplied clock signal, which controls the stepping of an internal finite-state machine that responds to incoming commands
. Some key features of SDRAM include:
- Synchronous Nature : SDRAM is synchronized with the clock speed of the processor, enabling faster data transfer rates
- Internal Finite State Machine : SDRAM has an internal finite state machine that pipelines incoming instructions, allowing it to operate more efficiently than asynchronous DRAM
- Higher Bandwidth : SDRAM has higher bandwidth, allowing for more data to be transferred simultaneously
- Lower Power Consumption : SDRAM consumes less power than its predecessor, dynamic random-access memory (DRAM)
There have been several generations of SDRAM, each with its own specifications. Some common types include SDR SDRAM (Single Data Rate SDRAM), DDR SDRAM (Double Data Rate SDRAM), DDR2, DDR3, and DDR4
. SDRAM is compatible with a wide range of computers, including desktops, laptops, and servers
