Samsung patents memory chip that saves data during power cuts
Samsung has filed a patent for a memory device that combines fast, temporary storage with slower, permanent storage. It includes a backup power source that keeps a specific part of the temporary storage alive long enough to move data to the permanent storage if the main power fails.
In the filing’s own words
A persistent memory device is disclosed. The persistent memory device may include a cache coherent interconnect interface. The persistent memory device may include a volatile storage and a non-volatile storage. The volatile storage may include at least a first area and a second area. A backup power source may be configured to provide backup power selectively to the second area of the volatile storage. A controller may control the volatile storage and the non-volatile storage. The persistent memory device may use the backup power source while transferring a data from the second area of the volatile storage to the non-volatile storage based at least in part on a loss of a primary power for the persistent memory device.
What exactly they claim (claim 1)
1. A memory device, comprising: a volatile storage including at least a first area and a second area; a non-volatile storage; and a controller to control the volatile storage and the non-volatile storage, wherein the second area of the volatile storage is selectively powered by a power source, and wherein the memory device is configured to transfer a data from the second area of the volatile storage to the non-volatile storage.
