HP helps birth analog-in-memory processor startup
TetraMem Inc. (Fremont, Calif.) is a startup that is developing analog-in-RRAM compute processor architecture.
The company was founded in 2018 by four engineers with common experience at Hewlett Packard working on ‘memristor’ research. Memristor is HP’s name for a non-linear two-terminal electrical component that is known more often as the resistive RAM.
The founders are: Glenn Ge, CEO; Miao Hu, CTO; Joshua Yang, chief scientific advisor and Qiangfei Xia, chief process advisor.
Like other analog-in-memory compute companies TetraMem uses the cross-point network for a ReRAM array to accelerate the multiply-accumulate operations in artificial intelligence neural networks.
Patented devices
The company claims its patented devices are a scalable technology optimized for low-power edge and endpoint inference can be 100s of times more efficient than Von Neumann architecture devices.
The company is claiming its neural processing unit (NPU) can deliver 20TOPS/W based on the INT8 datatype using mature technology nodes. This is expected to scale to 100TOPS/W at more advanced nodes.
TetraMem is pursuing an IP licensing business model including IP licensing, royalties, and custom design services.
The company has achieved three tape outs in silicon and expects mass production of chips including its technology around the end of 2023.
