Question

Which of the following statements about SRAM are true? Each correct answer represents a complete solution. Choose three.

Options

ASRAM is made of capacitors.
BSRAM is more expensive than DRAM.
CSRAM is made of a special circuit called a flip-flop.
DSRAM is used for caching.

Explanation

Static RAM (SRAM) is a type of memory chip made of a special circuit known as flip-flop. It is significantly faster than DRAM. Unlike DRAM memory chip circuits, it does not have to be refreshed because it uses the flip-flop circuit to store each bit. SRAM memory chips are generally used for caching. It has a disadvantage that it is more expensive than DRAM. Answer option A is incorrect. Dynamic Random Access Memory (DRAM) memory chip circuits are made of tiny capacitors. DRAM is slower than SRAM, as it needs to be refreshed.
