  17. Design Decisions • We decided to assign the two most difficult parts of our circuit to two people. • Anna and John – SRAM • Chris and Liew – Tea Encryption • We are also in the process of determining a sub-layout for the Encryption module • Looked at sensory amps and pre-charge transistors • Added the pre-charge transistors to each SRAM • Will use a sensory amp at the end of the SRAM to act as buffer

  18. Problems and Questions • The SRAM only being pulled to 1.2V instead of 1.8V
