EKF: PCI Express non volatile SRAM on a 2280 size M.2 module

EKF presents the M01-NVSRAM, a non volatile static RAM, organized as 1024k x 32bit, for PCI Express direct access (memory-mapped read/write to a linear address space, aka MMIO). Other than a normal SSD, the M01-NVSRAM is not a block device, and does not require a file system or drivers for data storage. The M01-NVSRAM supports memory-mapped I/O in a BYTE, WORD and DWORD mode instead.

The M01-NVSRAM is housed on a 2280 size M.2 module, suitable for any PCI Express based M.2 host connector (M-key). The data transfer is controlled by an FPGA. Automatic store is initiated on power-down. Data retention is guaranteed over 20 years, and no battery is needed for backup. The M01-NVSRAM is suitable e.g. for industrial applications with need for a reliable power fail safe data buffer.
