Problems solved by technology
[0003] However, due to the advancement of technology, the market demand capacity of flash memory is constantly increasing, so the sectors and pages that need to be processed to perform formatting increase accordingly, and the time required to perform formatting is lengthened. In the case of production equipment, the production capacity will be reduced due to the increase in formatted time, which will increase the production cost and pass it on to consumers, making it impossible for consumers to exchange for high-quality products at preferential prices

The invention discloses a method for formatting and initializing a Flash, which belongs to the field of computers and includes: scanning bad blocks of the Flash, reading the current bad block table from the EEPROM table of the flash memory; judging whether there is a bad block, and if there is a bad block, the Write the bad block into the bad block list, and remove the bad block from the sector; if it is not a bad block, keep it in the sector; update the bad block mapping table, and create an updated initialization bad block in the EEPROM of the memory stick Block table; after updating and initializing the bad block mapping table, establish a logical block / physical block mapping table; record the use of logical blocks in EEPROM; establish a video segment table in EEPROM. The technical scheme of the example of the present invention can realize the operation of writing while erasing during the formatting process of the Flash, which greatly improves the working efficiency of the Flash formatting.
Description
technical field [0001] The invention belongs to the field of computers, in particular to a method for high-speed processing flash memory, a device and a readable storage medium based on the method. Background technique [0002] Since the advent of flash memory technology, it has been gradually replacing erasable programmable read-only memory (EEPROM) or batteries in many portable devices with attractive features such as low power consumption, non-volatility, shock resistance, and high storage density. Nowadays, due to the increasing sophistication of semiconductor technology, the storage density and transmission speed of flash memory have grown by leaps and bounds. Therefore, flash memory can replace traditional storage media such as hard disk drives in many applications. [0003] However, due to the advancement of technology, the market demand capacity of flash memory is constantly increasing, so the sectors and pages that need to be processed to perform formatting increase...
