3T1D cell has been stated as a valid alternative to be implemented on L1 memory cache to substitute 6T, highly affected by device variability. In this contribution, we have shown that 22nm 3T1D memory cells present significant tolerance to high levels of device parameter fluctuation. Moreover, we have observed that the variability of the write access transistor has turn into the more detrimental device for the 3T1D cell performance. Furthermore, resizing and temperature control have been presented as some strategies to mitigate the cell variability.
