Memory

Basic Concepts

• Stores large number of bits
  • $m\times n$: m words of n bits each
  • $k={\log }_2(m)$ address input signals
    • aka $m=2^k$ words
• Memory access
  • r/w input selects either read or write
  • enable: read or write only when asserted
  • multiport: multiple accesses to different locations simultaneously

Types

• Read Only Memory
• Random Access Memory
• Register File
