Memory device, edge device handling storable data, and data management method

Abstract

According to one embodiment, data stored in past can be effectively used without being influenced by the characteristics and capacity of a memory storing storable data. Maintenance data are generated by managing a state in a memory area, alert notification data are transferred on the basis of the generated maintenance data, and/or at least a part of the data which are already stored in the memory area is transferred.

What is claimed is: 
     
         1 . A memory device including a data recordable area and a communication function,
 the memory device managing a state in the recordable area, discriminating possibility that data loss is to occur in the data, and determining next actual processing based on the discrimination.   
     
     
         2 . The memory device of  claim 1 , wherein the next actual processing based on the discrimination is to transmit alert notification data to the other device from the memory device. 
     
     
         3 . The memory device of  claim 1 , wherein the next actual processing based on the discrimination is to transmit at least the data in which the data loss is to occur to the other device from the memory device. 
     
     
         4 . The memory device of  claim 1 , wherein the discrimination is discrimination on substantial data amount which is recordable in the recordable area, and the next actual processing is to transmit the alert notification data. 
     
     
         5 . An edge device using data capable of being stored, for transmitting alert notification data, based on a state in a recordable memory area,
 the edge device discriminating possibility that data loss is to occur in data preliminarily recorded in the recordable memory area, and determining next actual processing, based on the discrimination.   
     
     
         6 . The edge device using data capable of being stored, of  claim 5 , wherein the next actual processing based on the discrimination is to transmit alert notification data to the other device from the edge device. 
     
     
         7 . The edge device using data capable of being stored, of  claim 5 , wherein the next actual processing based on the discrimination is to transmit at least the data in which the data loss is to occur to the other device from the edge device. 
     
     
         8 . The edge device using data capable of being stored, of  claim 5 , wherein the discrimination is discrimination on substantial data amount which is recordable in the recordable memory area, and the next actual processing is to transmit alert notification data. 
     
     
         9 . A data management method, comprising:
 managing a state of data in a recordable area in a first device,   discriminating possibility that data loss is to occur in the data; and   determining next actual processing, based on the discrimination,   
     
     
         10 . The data management method of  claim 9 , wherein the next actual processing based on the discrimination is to transmit alert notification data to the other device from the first device. 
     
     
         11 . The data management method of  claim 9 , wherein the next actual processing based on the discrimination is to transmit at least the data in which the data loss is to occur to the other device from the first device. 
     
     
         12 . The data management method of  claim 9 , wherein the discrimination is discrimination on substantial data amount which is recordable in the recordable area, the next actual processing is to transmit alert notification data.
