About Numem
Numem builds MRAM memory IP and chiplets for chip designers. Its NuRAM cores are an alternative to SRAM and Flash inside a system on chip. A second product, SmartMem, brings memory control and testing to other persistent memories, such as RRAM, PCRAM and Flash. Applications include wearables, AI, digital security and cameras, autonomous vehicles and data centers. Its website also lists an AI Memory Engine.
Numem is headquartered in Sunnyvale, California. Max Simmons is chief executive officer. Jack Guedj held that title in September 2023. That month, the company announced a Series A round led by Cambium Capital, with Doorga Capital also investing. Bill Leszinske, an operating partner at Cambium Capital, is a Numem board member.

Why Investors Backed Numem
Numem makes MRAM memory cores and chiplets that stand in for SRAM and Flash in chips. Cambium Capital led its Series A in September 2023, with Doorga Capital also investing. A Cambium operating partner is a Numem board member. The pitch is lower power draw and smaller chip area for AI and IoT systems.
The problem it targets
Bill Leszinske said AI, autonomous driving and smart IoT applications need a large increase in compute and memory. Numem's case is that memory must now balance power, performance and size. It also treats external DRAM access as power hungry. Packing more memory into the same area reduces how often a chip must reach for external DRAM.
What the product does
NuRAM includes complete memory management and control, so a designer can use it as simply as SRAM. It is 2 to 3 times smaller than traditional SRAM. Leakage power is 20 to 290 times lower, and standby power is 10 to 30 times lower. Writes run up to 500 times faster than most MRAM and RRAM. SmartMem functions can sit inside NuRAM as compute in memory, next to DSP and AI accelerator functions.
Progress so far
The Series A money is meant to speed the rollout of Numem's MRAM products and its patented SmartMem SOC subsystem. It also supports a new line of SmartMem SOC chiplets and chips. The company's website now lists NuRAM MRAM IP, an AI Memory Engine, and chiplets for wearables, data centers and automotive AI.
Who backs it
Cambium Capital led the round, and Doorga Capital also invested. Bill Leszinske, an operating partner at Cambium, is a Numem board member. He said Numem's IP building blocks and chiplets let advanced memories such as MRAM and RRAM reach new levels of performance and low power for new workloads. Jack Guedj, chief executive officer at the time, said Cambium knows deep tech well and understands the AI and memory sectors.
