Neuromorphic device and electronic device including the same

A neuromorphic device, comprising:

• a plurality of cell tiles, each of the plurality of cell tiles including:
• a cell array including a plurality of memory cells configured to store weights of a neural network,
• a row driver connected to the plurality of memory cells via a plurality of row lines, and
• at least one cell analog-digital converter (ADC) connected to the plurality of memory cells via a plurality of column lines, the at least one cell ADC configured to convert cell currents read via the plurality of column lines into a plurality of pieces of digital cell data;
• a reference tile distinct from the plurality of cell tiles, the reference tile including:
• a reference cell array including a plurality of reference cells, the reference cell array distinct from the cell array of each of the plurality of cell tiles,
• a reference row driver connected to the plurality of reference cells via a plurality of reference row lines, the reference row driver distinct from the row driver connected to the plurality of memory cells, and
• at least one reference ADC connected to the plurality of reference cells via a plurality of reference column lines, the at least one reference ADC configured to convert reference currents read via the plurality of reference column lines into a plurality of pieces of digital reference data, wherein the at least one reference ADC is distinct from the at least one ADC connected to the plurality of memory cells;
• and
• at least one comparator circuit configured to compare the plurality of pieces of digital cell data with the plurality of pieces of digital reference data.
