20130148457 | FAST STARTUP HYBRID MEMORY MODULE - A memory device is provided comprising: a volatile memory device, a non-volatile memory device, a memory control circuit volatile memory controller coupled to the volatile memory device and non-volatile memory device, and a backup power source. The backup power source may be arranged to temporarily power the volatile memory devices and the memory control circuit upon a loss of power from the external power source. Additionally, a switch may serve to selectively couple: (a) a host memory bus to either the volatile memory device or non-volatile memory device; and (b) the volatile memory device to the non-volatile memory device. Upon reestablishment of power by an external power source from a power loss event, the memory control circuit is configured to restore data from the non-volatile memory device to the volatile memory device prior to a host system, to which the memory device is coupled, completes boot-up. | 06-13-2013 |
20130142001 | BATTERY-LESS CACHE MEMORY MODULE WITH INTEGRATED BACKUP - A memory module is provided comprising a substrate having an interface to a host system, volatile memory, non-volatile memory, and a logic device. The logic device may receive the indicator of an external triggering event and copies data from the volatile memory devices to the non-volatile memory devices upon receipt of such indicator.
