Question

Why do tiny MOSFETs that are used to move charge onto and off the capacitors limit the speed with which a computer can store or retrieve bits from its dynamic memory?

Answer 1

MOSFETs are poor conductors of electrical current hence it takes time to store or retrieve the charge that is in the memory capacitors.

Step-by-step explanation:

Dynamic Random Access Memory (DRAM) stores information bits in a memory cell. The cell is made up of a capacitor and a MOSFET transistor. The state of the capacitor can represented by the bits 1 and 0. 1 represents a fully charged capacitor while 0 represents its discharged state .Since MOSFETs are poor conductors of current it takes time to charge the capacitor and also discharge it , this in turn limits the speed at which the computer can store and retrieve bits from its dynamic memory.
