MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -In static random-access memory (SRAM), another type of semiconductor memory, the data is not stored as charge on a capacitor, but in a pair of a cross-coupled inverters, so SRAM does not need to be refreshed.

Detailed explanation-2: -SRAM (static RAM) is a type of random access memory (RAM) that retains data bits in its memory as long as power is being supplied. Unlike dynamic RAM (DRAM), which must be continuously refreshed, SRAM does not have this requirement, resulting in better performance and lower power usage.

Detailed explanation-3: -The correct answer is Dynamic Random Access Memory (DRAM). It must be refreshed many times per second to store information, otherwise, it will lose what it is holding. Hence, Option 2 is correct. It is the most common type of memory in use today.

Detailed explanation-4: -The correct answer is Both SRAM and DRAM are random access memory. Random-access memory comes in both SRAM and DRAM varieties. Both RAMs were developed to give different programmes access to data storage. A form of RAM known as SRAM (Static Random Access Memory) saves data bits in the memory when it is powered on.
