DRAM

What does "RAM (random access memory)" in DRAM mean?

  1. AMemory in which any address can be read or written directly in roughly the same time
  2. BMemory that can only be read sequentially from the beginning
  3. CRead-only memory that cannot be rewritten
Show answer and explanation

Answer: A. Memory in which any address can be read or written directly in roughly the same time

Random access means that by specifying an address, any location can be accessed directly regardless of order. It contrasts with sequential access, where you must go through the data in order, as with magnetic tape. Read-only memory is called ROM.

  • A. Correct. Any address can be accessed directly.
  • B. Memory that can only be read in order is sequential-access memory.
  • C. Read-only memory is ROM.
