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. |
