Tail data page searching method, device and equipment and readable storage medium

The invention provides a tail data page searching method, device and equipment and a readable storage medium. The method comprises the following steps: step S10, determining an available flash memory bare chip; step S20, finding a tail data page of the first flash memory bare chip in the available flash memory bare chips through a binary search method; s30, detecting whether the page number of the tail data page is the maximum page number or not; s40, if yes, recording the page number of the tail data page, and executing the step S50; step S60, if not, scanning a super page later, and detecting whether the state of the super page is completely empty or not; step S70, if the flash memory bare chip is not completely empty, determining a tail data page of the next flash memory bare chip, and returning to the step S30; step S80, if the page number of the tail data page is empty, recording the page number of the tail data page, and executing step S50; and S50, searching a target flash memory bare chip with data in the page number from the available flash memory bare chips, and taking the tail data page of the flash memory bare chip with the maximum label in the target flash memory bare chip as a real tail data page. According to the method, the time for recovering the normal working state after the chip is powered on again can be shortened.
