Abstract

The invention discloses a method and device for improving flash memory programming efficiency, a storage medium and a terminal. The method comprises the following steps: firstly, switching a voltage applied to an address line to a low voltage, and then traversing verification of all data needing to be programmed; after the verification is finished, finding an address needing to be programmed in the flash, and then switching the voltage applied to an address line to a high voltage; executing a programming operation on an address needing to be programmed in the flash. Although different addresses needing to be programmed in the flash need to be switched when programming operation is performed on the different addresses in the flash, and a cyclic charging and discharging process caused by voltage boosting and voltage reducing of an address line exists, voltage boosting and voltage reducing switching does not need to be performed on the addresses which do not need to be programmed in the flash any more, so that the programming efficiency is improved; and when the amount of data needing to be programmed is large enough, the effect of improving the programming efficiency is very obvious.

Description

technical field [0001] The present invention relates to the technical field of flash, in particular to a method, device, storage medium and terminal for improving the programming efficiency of flash memory. Background technique [0002] like figure 1 As shown, it is the general programming process of Nor flash, receiving programming instructions and data, then verifying the data and recording the address to be programmed, and then programming. [0003] In the prior art, in order to ensure the normal operation of the device, the voltage of the address line needs to be switched from high voltage to low voltage when switching between different addresses, and after the address switching is completed, the voltage of the address line will rise again, and then data verification is performed , when the address that needs to be programmed is verified, the address is programmed, and after programming, the voltage of the address line is switched to low voltage to switch the address......
