SMART’s NV-CMM-E3S non-volatile memory module with built-in backup power source utilizes the Compute Express Link (CXL)® 2.0 standard in an E3.S 2T form factor. It uses a CXL x8 CXL controller as well as a SMART NV-CXL Controller and 2Rx4 Buffered DDR4 DRAM, which allows the host to access the DRAM via the CXL x8 interface during runtime. In the event of a catastrophic failure, the module will back up the DRAM data into the NAND devices using power from its onboard Energy Source Module (ESM). When power is restored, the NV-CMM-E3S will then copy data from the NAND devices to the DRAM in order to enable continuous operation.
