FLASH BACKED DRAM MODULE STORING PARAMETER INFORMATION OF THE DRAM MODULE IN THE FLASH

摘要

A device includes volatile memory; one or more non-volatile memory chips, each of which is for storing data moved from the volatile-memory; an interface for connecting to a backup power source arranged to temporarily power the volatile memory upon a loss of power from a primary power source; a controller in communication with the volatile memory and the non-volatile memory, wherein: the controller is programmed to move data from the volatile memory to the non-volatile memory chips upon a loss of power of the primary power source of the volatile memory; and parameters describing the volatile memory are stored in at least one of the non-volatile memory chips that store the data moved from the volatile memory. In some aspects the parameters include serial presence detect information.
