Abstract

The present invention is applicable to the field of electronic technology, and provides a method and device for data storage. The method includes: acquiring data to be stored; determining the data type of the data to be stored and the storage attribute corresponding to the data type; wherein, The storage attribute includes frequent storage and infrequent storage; if the storage attribute is the frequent storage, then save the data to be stored to an external memory; if the storage attribute is the infrequent storage, save the The data to be stored is saved to the flash memory. The technical solution of the present invention can effectively utilize the advantages of long read and write life, fast read and write speed and low power consumption of the external memory by storing the frequently stored data in the external memory, and at the same time store the infrequently stored data in the internal flash memory , reducing the space requirement for the external memory, thereby reducing hardware costs while ensuring real-time data storage.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to a data storage method and device. Background technique [0002] At present, all power products need to support non-volatile storage functions, that is, in the event of a power system failure and power outage, it can ensure that power-related parameters such as power and recorded real-time data will not be lost. [0003] Usually, the non-volatile storage function of power products is realized by means of external ferroelectric memory or internal flash memory. However, only using the external ferroelectric memory to save all real-time data requires a large ferroelectric capacity and high cost; only using the internal flash memory for storage, for data that needs to be stored once per second, such as electric energy, use the flash memory for frequent storage Sometimes the same type of data may be stored in different addresses, which is inconvenient to read and cannot meet actua...
