Microchip Unveils SuperFlash memBrain Memory Solution

Microchip has worked with WITINMEM to incorporate Microchip’s memBrain analog in-memory computing solution, based on SuperFlash technology, into WITINMEM’s ultra-low-power SoC.

Microchip Technology and its Silicon Storage Technology (SST) subsidiary have declared that its SuperFlash memBrain neuromorphic memory solution has solved the problem for the WITINMEM neural processing SoC, the first in volume production that enables sub-mA systems to reduce speech noise and recognize hundreds of command words, in real-time and immediately after power-up.

“WITINMEM is breaking new ground with Microchip’s memBrain solution for addressing the compute-intensive requirements of real-time AI speech at the network edge based on advanced neural network models,” said Shaodi Wang, CEO of WITINMEM. “We were the first to develop a computing-in-memory chip for audio in 2019, and now we have achieved another milestone with volume production of this technology in our ultra-low-power neural processing SoC that streamlines and improves speech processing performance in intelligent voice and health products.”

“We are excited to have WITINMEM as our lead customer and applaud the company for entering the expanding AI edge processing market with a superior product using our technology,” said Mark Reiten, vice president of the license division at SST. “The WITINMEM SoC showcases the value of using memBrain technology to create a single-chip solution based on a computing-in-memory neural processor that eliminates the problems of traditional processors that use digital DSP and SRAM/DRAM-based approaches for storing and executing machine learning models.”

The SoC features computing-in-memory technology for neural networks processing including speech recognition, voice-print recognition, deep speech noise reduction, scene detection, and health status monitoring.

WITINMEM, in turn, is working with multiple customers to bring products to market during 2022 based on this SoC.

Microchip’s memBrain neuromorphic memory product is optimized to perform vector-matrix multiplication (VMM) for neural networks. It enables processors used in battery-powered and deeply-embedded edge devices to deliver the highest possible AI inference performance per watt.

This is accomplished by both storing the neural model weights as values in the memory array and using the memory array as the neural compute element.

WITINMEM has leveraged SuperFlash technology’s floating gate cells’ nonvolatility to power down its computing-in-memory macros during the idle state to further reduce leakage power in demanding IoT use cases.
