Embodiment Construction

[0014] see figure 1 , a memory card data processing system for processing data in a memory card 10. The memory card 10 includes a controller 11 and a flash 13 . The controller 11 communicates with a host chip 30 . The host chip 30 can write data into the flash 13 or read data from the flash 13 through the controller 11 .

[0015] Please also see figure 2 , the controller 11 includes a storage module 110 , a loading module 112 , a read-write module 115 and an execution module 116 .

[0016] The flash 13 includes several blocks, each block includes several pages, and each page stores a firmware program. Each physical block corresponds to a physical block address. A mapping table is stored in the storage module 110 . The mapping table records the corresponding logical relationship between each physical block address and a logical address. The flash 13 also includes a secondary loading module 132 .

[0017] The read-write module 115 is used for writing the data of the loa...

Abstract

The invention discloses a memory card data processing method, and aims to process a firmware program in a memory card. The memory card data processing method comprises the following steps: writing data of a loading module into a controller of the memory card; writing data of a secondary loading module to flash of the memory card; loading through the loading module to start the secondary loading module; loading by the secondary loading module to start the firmware program; and implementing the firmware program. The invention further discloses a memory card data processing system.

Description

technical field [0001] The invention relates to a memory card data processing method and system. Background technique [0002] When the memory card is mass-produced, the firmware program (firmware) is written into the flash. The firmware program determines the internal structure and characteristics of the flash. The firmware program is loaded and started by the corresponding loader (boot) to perform various functions. Flash manufacturers are upgrading the flash firmware program year by month to improve the internal structure and features of the flash, and the corresponding loading program also needs to be updated synchronously. However, the loading program is usually solidified in the control chip of the memory card, and it is difficult to update it synchronously. Contents of the invention [0003] In view of the above, it is necessary to provide a memory card data processing method and system for synchronously updating firmware programs. [0004] A memory card data pr...
