Neural Network Accelerator in DIMM Form Factor

The technology relates to a neural network dual in-line memory module (NN-DIMM), a microelectronic system comprising a CPU and a plurality of the NN-DIMMs, and a method of transferring information between the CPU and the plurality of the NN-DIMMS. The NN-DIMM may include a module card having a plurality of parallel edge contacts adjacent to an edge of a slot connector thereof and configured to have the same command and signal interface as a standard dual in-line memory module (DIMM). The NN-DIMM may also include a deep neural network (DNN) accelerator affixed to the module card, and a bridge configured to transfer information between the DNN accelerator and the plurality of parallel edge contacts via a DIMM external interface.
