Embodiment Construction

[0019] First, see image 3 . image 3 is a schematic diagram of memory planning according to an embodiment of the present invention. It can be seen from the figure that a memory is divided into three parts: fixed program block, callback function entry point block and application program block. System, communication protocol, driver and font, image, graphic file, etc. The application program block stores the application programs (MMI) that need to be modified or changed. The callback function entry point block is a callback function entry point matrix, which records the starting addresses of all callback functions. When a callback function is called by the fixed program, it is through its starting address.

[0020] see again Figure 4 , when a fixed program A or B in the fixed program block calls the callback function A" or B" in the application program block, it is necessary to first go to the callback function entry point block to find a callback function comparison tabl...

Abstract

A flash memory and a method for program planning and repeating burnt record are disclosed, in which the method is used for making a modified application program be translated and edited, and thus be burnt recorded on a planned flash memory. The flash memory includes a fixed program block containing a program burnt recorded integrally and having no need to be modified any more; an application program block containing a modifiable or alternative application program; and a recall function entry point block containing a recall function entry point matrices which records a start address value in the application program block when all the recall function is recalled by the fixed program. When repeating the burnt record, only the recall function entry point block and program code of the application program block are burnt recorded.

Description

technical field [0001] The present invention relates to a flash memory and a method for program planning and repeated programming thereof, in particular to a flash memory and a method for repeatedly programming a program in the flash memory after planning a program entry point matrix in the flash memory. Background technique [0002] Flash memory is a type of memory that most handheld devices use to store the operating system. Flash memory is also used in mobile phones, digital cameras, LAN converters, PC cards, set-top boxes, and embedded controllers. Flash memory writes an entire block at a time during programming, which is faster than EEPROM that writes one byte at a time. Modern computers use flash memory as a component for storing the BIOS, so that the BIOS can be updated by ordinary users without using a special burner (Burner). [0003] With the increasing application and demand of MMI (man-machine interface), the complexity and length of software also increase, esp...
