The base epitaxial layer is dopant free. The doped epitaxial layer abuts the first fin in the first region and the second fin in the second region.

Techniques described herein provide memory redundancy. For example, the memory block for each pixel can be partitioned into multiple memory bins, and the number of memory bins can be larger than the number of time bins. Once a faulty memory cell is identified, an address associated with the memory bin that has the faulty memory cell can be skipped by an address generator. As such, the faulty memory cell is not used to store time-of-fight (ToF) information.
