PRODUCTION DATA.
The TS3DDR4000 can be used in the NVDIMM application to provide server systems reliable data backups when the system encounters power-failure conditions. Figure 19 depicts a typical NVDIMM design utilizing the TS3DDR4000.
In normal system operation, the TS3DDR4000 routes the DDR signals between the system and the DRAM for normal data access. When the system encounters power failure, the charge stored in the battery or the super capacitor is used to power the NVDIMM controller, which configures the TS3DDR4000 to save the data from DRAM into the NAND Flash. The NAND Flash is non-volatile in nature, so the data stored internally stays intact even when the power goes away eventually. When the system power comes back on, the NVDIMM controller can re-route the data from the NAND Flash through the TS3DDR4000 back into the DRAM and can subsequently re-start the normal system operation.
