DDR4 NVDIMM-N DESIGN SPECIFICATION	JESD248A	Mar 2018
This standard defines the electrical and mechanical requirements for 288-pin, 1.2 Volt (VDD), Double Data Rate, Synchronous SDRAM Nonvolatile Dual In-Line Memory Modules with NAND Flash backup (DDR4 NVDIMM-N). A DDR4 NVDIMM-N is a Hybrid Memory Module with a DDR4 DIMM interface consisting of DRAM that is made nonvolatile through the use of NAND Flash. NVDIMM-N modules adhere to the Byte Addressable Energy Backed Interface Standard, JESD245, that provides detailed logical behavior, interface, and register definitions. These DDR4 NVDIMM-N modules are intended for use as main memory or storage when installed in PCs. This standard is used in conjunction with JESD245.

BYTE ADDRESSABLE ENERGY BACKED INTERFACE	JESD245E	Apr 2022
This standard specifies the host and device interface for a DDR4 NVDIMM-N, which is a DIMM that achieves non-volatility by copying SDRAM contents into non-volatile memory (NVM) when host power is lost using an Energy Source managed by either the module or the host. This standard is used in conjunction with JESD248. Item 2233.54G Committee(s): JC-45.6 Free download. Registration or login required.
