RAM Guidelines

• Less than 32 words is best for fastest performance

  • 32x1 or 16x2 RAM fits in one CLB
    • Delays are short (one level of logic)
  • Data and output MUXes are required to expand depth

• Less than 256 words recommended per RAM

  • Use external memory for 256 words or more

• Width easily expanded

  • Connect the address lines to multiple blocks

• Recommendation: Use less than 1/2 of max memory resources

  • Maximum memory uses all logic resources of CLBs
