The test chip will enable the correlation of the simulation models to the FinFET process and contains test structures, standard cells, a PLL and embedded SRAMs. The memory instances include high-density SRAMs designed to operate at very low voltages and high-speed SRAMs to validate the process performance.
The housing of the speaker is made from 8mm MDF (Medium-Density fiberboard) manufactured wood which allows for VLD (Very Low Distortion) technology when listening to music at a high volume.
