InfiniteMemory — Product Overview

InfiniteMemory is a hardware CXL memory expander that leverages NVMe SSDs as its backing storage. It expands the system memory capacity by utilizing SSD storage as a CXL-attached memory, transparently accessible to applications.

Key Features

  • CXL 3.0 Type 3 memory expander device
  • SSD-backed large capacity memory (TB-scale)
  • Hardware-managed DRAM cache for hot data
  • DAX (Direct Access) support for byte-addressable access
  • Transparent to applications via standard memory interfaces

Architecture (high level)

InfiniteMemory architecture: Host CPU — CXL 3.0 — InfiniteMemory with DRAM cache — NVMe — SSD

Hot data is served from the on-device DRAM cache (CXL latency); cold data is fetched from the backing SSD.
