Zeno Semiconductor›Zeno Semiconductor› offers Bi-SRAM

Bi-SRAM uses a single transistor as the memory bitcell, making it approximately 3x-5x smaller than conventional 6-transistor SRAM at the same technology node. The technology is bi-stable, meaning it does not require refresh operations like DRAM. It is manufactured on standard CMOS logic processes with no new materials or equipment, and no changes to existing libraries and IPs.

Zeno has demonstrated the technology at 28nm and 14/16nm FinFET nodes from multiple foundries. The business model is to license the technology to semiconductor companies and foundries, who can implement their own memory macros or contract with Zeno for development.
