During operation the DRAM or SRAM is used in a system the same way that any DRAM or SRAM would be used. When power is interrupted the controller moves all of the data from the DRAM or SRAM to the flash using the backup power from the battery or super-capacitor. When power is restored, the controller moves the contents of the flash back into the SRAM or DRAM and the processor can resume operation where it left off.
In some ways it’s storage and in some ways it’s memory, so Continue reading
Viking Technology on Wednesday announced that the company has arranged with SuperMicro to deliver solutions that should solve issues key to flash storage array designers. Supermicro will ship server boards that have all the hooks necessary to support Viking’s nonvolatile DDR3 DIMMs without users having to wait for this kind of support to arrive in servers based on the standard Intel platform.
Viking’s marketing folks tell me that NV-DIMM support is something that its customers have been asking for, and that it will be a standard component of Continue reading
