DRAM

What does F mean in '6F²', used to express DRAM cell area?

  1. AFarad (the unit of capacitance)
  2. BThe number of fins
  3. CThe minimum feature size
Show answer and explanation

Answer: C. The minimum feature size

F represents the minimum feature size, and cell area is expressed as a multiple of F squared. 6F² means an area six times the square of the minimum feature size. DRAM cell structures have improved from 8F² to 6F², and research aims to achieve 4F².
