A neuromorphic package device includes a systolic array package and a controller. The systolic array package includes neuromorphic chips arranged in a systolic array along a first direction and a second direction. The controller communicates with a host controls the neuromorphic chips. Each of the neuromorphic chips sequentially transfers weights of a plurality layers of a neural network system in the first direction to store the weights. A first neuromorphic chip performs a calculation based on stored weights therein and an input data received in the second direction, and provides a result of the calculation to at least one of a second neuromorphic chip and a third neuromorphic chip which are adjacent to the first neuromorphic chip. The at least one of the second and third neuromorphic chips performs a calculation based on a provided result of the calculation and stored weights therein.
