MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Because SRAM does not need to refresh, it is typically faster. The average access time of DRAM is about 60 nanoseconds, while SRAM can give access times as low as 10 nanoseconds.

Detailed explanation-2: -Cache memory is the fastest system memory, required to keep up with the CPU as it fetches and executes instructions. The data most frequently used by the CPU is stored in cache memory.

Detailed explanation-3: -The fastest access time is found in semiconductor memories. Magnetic tapes, magnetic discs, compact discs, and other older memory have higher access times.

Detailed explanation-4: -Cache memory is faster than main memory. It consumes less access time as compared to main memory. It stores the program that can be executed within a short period of time. It stores data for temporary use.

Detailed explanation-5: -Explanation: SRAM will retain data as long it is powered up and it does not need to be refreshed as DRAM. It is designed for low power consumption and used in preference. DRAM is cheaper than SRAM but it is based on refresh circuitry as it loses charge since the capacitor is the storage element.
