Abstract

The invention provides a firmware code execution method, a memory storage device and a memory control circuit unit. The method comprises the following steps: executing a firmware code in a read-only memory; after executing the first part of the firmware code, querying reference information in a reference memory according to index information in the firmware code; and determining to continue to execute the second part of the firmware code or switch to execute the alternative program code in the reference memory according to the reference information so as to finish the startup program. Therefore, the use flexibility of the memory storage device (or the memory control circuit unit) can be improved, and / or the service life of the memory storage device (or the memory control circuit unit) canbe prolonged.

Description

technical field [0001] The invention relates to a memory management technology, in particular to a firmware code execution method, a memory storage device and a memory control circuit unit. Background technique [0002] Digital cameras, mobile phones, and MP3 players have grown rapidly in recent years, making consumers' demand for storage media also increase rapidly. Since the rewritable non-volatile memory module (for example, flash memory) has the characteristics of data non-volatility, power saving, small size, and no mechanical structure, it is very suitable for built-in Among the various portable multimedia devices listed above. [0003] Most memory storage devices or their control chips store firmware codes for booting. When starting up, the control chip of the memory storage device can execute the firmware code, so as to complete the booting procedure or startup procedure such as system initialization. Generally speaking, before the memory storage device or its con...
