Abstract:
A neuromorphic processor may include at least a first synapse element. The first synapse element may include a first bit cell and a second bit cell, the first bit cell connected to a first bitline, a first inverted bitline, a first wordline, and a first inverted wordline, and the second bit cell connected to the first bitline, the first inverted bitline, a second wordline, and a second inverted wordline. The first synapse element may be configured to receive a first input through the first wordline, the first inverted wordline, the second wordline, and the second inverted wordline, store a first synapse value in the first bit cell and the second bit cell, perform a calculation operation using the first input and the first synapse value, and output a result of the calculation through the first bitline and the first inverted bitline.
