Static power consumption

Advantage of static CMOS SRAM with respect to resistive and depletion load

  1. Lowest static power dissipation

  2. Compatibility with current logic process

  3. Superior noise margin

  4. Better switching speed

Disadvantages

  1. Added complexity of PMOS process

  2. Slightly …
