Problems solved by technology

[0003] The problem arising from the adoption of the above technology is that the main chip needs to have a set of bus interfaces with built-in integrated circuits for accessing the EEPROM, which occupies chip hardware resources to a certain extent.
Because of the characteristics of flash memory erasing and writing (the same address area, if the data is updated again, it must be erased, and the unit of the erased data size is the entire chip or block or sector, there is no byte erase Function)

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] In a preferred embodiment, as figure 1 As shown, a data storage method is proposed, which is applied to the flash memory in the display device, which may include:

[0021] Step S1, dividing the flash memory into a first user storage area and a second user storage area to store structured data;

[0022] Step S2, cyclically and alternately storing structured data between the first user storage area and the second user storage area according to a preset policy.

[0023] In the above technical solution, due to the use of structured data, it is easy to distinguish structured data from single data, so it is easy to realize the distinction and search of structured data;

[0024] In a preferred embodiment, the preset strategy can be:

[0025] Store structured data in the first user storage area or the second user storage area, when either the first us...

Abstract

The present invention relates to a data storage technology, and in particular to a data storage method, which is applied to a flash memory in a display device. The method comprises: Step S1: dividinga flash memory into a first user storage area and a second user storage area so as to store the structured data; and Step S2: alternately storing the structured data in a cyclical manner between the first user storage area and the second user storage area according to a preset strategy. According to the method provided by the present invention, newly stored data can be easily found out, the problem of data loss caused by erased outage is avoided, and the writing speed is fast and the reliability is high.

Description

technical field [0001] The invention relates to a data storage technology, in particular to a data storage method. Background technique [0002] Traditional TVs usually use two methods to store user data: one is to connect the EEPROM through the built-in integrated circuit bus to store user-adjustable data, such as the adjustment values ​​of items in the menu (brightness, Contrast, volume, etc.), after adjustment, through the built-in integrated circuit protocol, write to the EEPROM to achieve the function of data storage; secondly, set aside a space in the program memory for the storage of user data , each data storage update changes the data at the original address of the data storage. [0003] The problem arising from the adoption of the above technology is that the main chip needs to have a set of bus interfaces with built-in integrated circuits for accessing the EEPROM, which occupies chip hardware resources to a certain extent. An external device is connected to the ...
