A high-speed flash memory processing method, equipment based on the method and a readable storage medium

Abstract

The invention discloses a Flash formatting and initializing method, which belongs to the field of computers and comprises the following steps of: scanning a bad block by a Flash, and reading a currentbad block table from an EEPROM (Electrically Erasable Programmable Read-Only Memory) table of a flash memory; Judging whether a bad block exists or not, if yes, writing the bad block into a bad blocklist, and removing the bad block from the sector; If not, Remaining it in the sector; Updating the bad block mapping table, and establishing an updated initialized bad block table in an EEPROM of a memory bank; After updating the initialized bad block mapping table, establishing a logic block / physical block mapping table; Recording the use condition of the logic block in the EEPROM; And establishing a video clip table in the EEPROM. According to the technical scheme provided by the embodiment of the invention, the operation of erasing and writing at the same time can be realized in the formatting process of the Flash, so that the working efficiency of the formatting of the Flash is greatly improved.

Description

technical field [0001] The invention belongs to the field of computers, in particular to a method for high-speed processing of flash memory, a device and a readable storage medium based on the method. Background technique [0002] Since the advent of flash technology, it has gradually replaced Erasable Programmable Read-Only Memory (EEPROM) or batteries in many portable devices with fascinating features such as low power consumption, non-volatility, shock resistance, and high storage density. 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 for flash memory is constantly increasing, so the sectors and pages that need to be processed for formatting are also increased, which in turn increases the time required for formatting. In the case of production equ...

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
