This technology, called FleXIMM, is a digital compute-in-memory (DCIM) circuit allowing better weight, computer density, and energy efficiency.
Data processing in digital computers requires increasingly complex functionalities calling for unprecedented energy efficiency of edge hardware. Digital compute-in-memory (DCIM) circuits are designed to support complex circuits improving the computational speed and energy efficiency of computers. Conventional DCIM contains a large silicon area, and reducing the area often results in a degradation in compute density and energy efficiency. There is a need for a more efficient in-memory computing architecture.
This technology is a DCIM circuit called FleXIMM which overcomes prior trade-offs between weight density, compute density and energy efficiency. It uses an efficient bitcell-access scheme and an adder-optimization technique which introduces a circuit without any weight density/computer density trade-off made in 28nm. It also enables 16-128 input dimensions without degradation of compute density.
