Our Technology

ReRAM

Purpose-built memory and silicon architectures engineered for performance, security, and hardware-level verifiability.

Hardware Wallets

Open-source from chip RTL to application layer. IRIS-inspectable silicon, verifiable firmware. No closed components.

Seedless key management on a secure element. 10x faster than cloud-based MPC. Local threshold signing with no cloud dependency.

Why ReRAM is Fundamental

Traditional flash memory was designed for data storage, not for safeguarding cryptographic secrets. ReRAM changes the physics of what is possible.

High Density

Terabyte-scale on-chip storage with minimal layout overhead. Ultra-dense, stackable 3D cross-point arrays.

Energy Efficient

5× less energy than eFlash, 20× less than NAND, 30× less than SPI Flash, and 40× less than BLE.

High Performance

20ns read, 12μs write, no erase latency. 100× faster reads, and 1,000× faster writes than traditional memory.

Enhanced Security

Tamper-resistant storage for cryptographic keys. Prevents extraction and supports secure keys.

ReRAM Highlights

World's First Secure Processing Unit (SPU)

Innovative products leveraging crossbar architecture for secure computing.

DARIC SPU

DARIC is CrossBar’s purpose-built secure processing unit, combining compute, cryptographic acceleration, and ReRAM-based memory into a single monolithic architecture. Designed from the ground up for security and performance, it eliminates the need for fragmented systems and exposed interconnects.

Built on advanced-node ReRAM, DARIC enables physically secure key storage, high-speed execution, and long-term data integrity within one unified chip.

• Integrated ReRAM for secure, high-retention memory

• On-chip cryptographic engine (ECDSA, SHA, PQC-ready)

• Monolithic design reduces attack surface

• Open architecture for verifiability and auditability

Multi-Party Computation moves key management from a single secret to a distributed protocol. CrossBar's E-MPC is the first implementation that runs entirely on a secure element — no cloud required.

• No seed phrase or single point of compromise

• Local, device-based MPC signing

• Flexible threshold configuration (T-of-N)

• Built on DARIC secure processing architecture

Seedless. Local. Sovereign.
