Which of the following are the performance parameters of memory ?

(i) Latency
(ii) Memory Cycle Time
(iii) Transfer Rate

  • A.(i) and (ii)
  • B.(ii) and (iii)
  • C.(i) and (iii)
  • D.(i), (ii) and (iii)

Answer: D

All three are memory performance parameters, so the answer is (i), (ii) and (iii).

William Stallings gives three performance parameters for memory: access time (latency), the time to perform a read or write; memory cycle time, the access time plus any further time before a second access can start; and transfer rate, the rate at which data can be moved into or out of the memory unit.

Each option that leaves one of them out is therefore incomplete.
