Question

Which of the following memories has more speed in accessing data?

(a) SRAM

(b) DRAM

(c) EPROM

(d) EEPROM

I got this question in an international level competition.

Question is from Memory Technology of Embedded Systems in section Memory Systems of Embedded Systems

Answer 1

Right choice is (a) SRAM

Easiest explanation: SRAM have more speed than DRAM because it has 4 to 6 transistors arranged as flip-flop logic gates, that is it can be flipped from one binary state to another but DRAM has a small capacitor as its storage element.
