The presentation deals with classification of logic devices based on electron spin as a computational variable. Requirements for logic devices are reviewed. Specifically we focus on a) concatenability (output of one device can drive another) and b) the complete set of Boolean operators (NOT, AND, OR, or equivalent). Based on their inputs and outputs and schemes of interconnection, spintronic devices are classified into four groups. Proposed and demonstrated devices belonging to each group are considered in more detail. Their relative advantages and disadvantages are considered.
