MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The main memory is generally made up of DRAM chips. Each cell of a SRAM contains 4 or 6 MOS transistors. Each cell of a DRAM contains 1 MOS transistor and 1 capacitor. Due to complex internal circuitry, less storage capacity is available compared to the same physical size of the DRAM memory chip.

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: -SRAM is most often found in hard drives as disc cache. It is also found in compact discs (CD’s), printers, modem routers, digital versatile discs (DVD’s) and digital cameras. SRAM’s access time is a lot faster than DRAM’s.
