DDR4 NVDIMM-P BUSS PROTOCOL |
JESD304-4 | Nov 2020 |
TEMPORARILY REMOVED 12/8/20. If your downloaded proir to this date please discard this iwill be republished shortly as JESD304-4.01An NVDIMM-P device is defined as a LRDIMM memory module which provides host controller access to DRAM and/or other memory devices such as persistent memory. A transactional protocol is described for NVDIMM-P, which may be used on a DDR interface allowing operation of both standard DRAM modules and NVDIMM-P modules on the same channel. Item 2233.98K.
