Memory - Basic Concepts

• Stores large number of bits
  • m x n : (m개의 words) 와 (n개의 bits per words)
  • k개의 address input signals
    • $k = log_2(m)$
• Example
  • 4096 x 8 memory
    • 32,768 개의 bits
    • 12 address input signals
    • 8 input/output data signals
• Memory Access
  • enable(chip select)
  • R/W : Read or Write only when asserted
  • multiport
