S ram
Synchronous Dynamic Random-Access Memory (SDRAM) and Dynamic Random-Access Memory (DRAM) are both types of RAM used in computers and other devices, but they have some key differences: 1. **Synchronization**: - **SDRAM**: Synchronous with the system clock. It synchronizes its operations with the CPU's clock cycle, allowing for more efficient data processing. - **DRAM**: Asynchronous. It does not rely on the system clock, which can result in slower data access times compared to SDRAM. 2. **Speed**: - **SDRAM**: Generally faster due to its synchronous nature. It can queue up multiple instructions and execute them in rapid succession, leading to higher performance. - **DRAM**: Slower as it processes instructions one at a time without synchronization to the system clock. 3. **Technology Generation**: - **SDRAM**: A newer technology compared to traditional DRAM. It has evolved through various generations, such as DDR (Double Data Rate) SDRAM, DDR2, DDR3, DDR4, and DDR5,
