Embodiments of the present disclosure provide a method for optimizing a flash memory chip and a related apparatus. The method comprises, after completing write training of a nonvolatile flash interface (NFI) and establishing a data strobe signal (DQS) trigger point that triggers a memory to identify an electrical level state of a write data signal (DQ) corresponding to the DQS trigger point, determining whether a trigger condition for monitoring the NFI is met, wherein the trigger condition is related to working environmental data of the NFI; upon determining that the trigger condition for monitoring the NFI is met, writing test data to the memory and performing a margin test on the NFI to determine whether the NFI passes a margin test; and upon determining that the NFI does not pass the margin test, initiating interface retraining of the NFI. In this way, the NFI bus channels can be optimized without disk disconnection.

Safe box

This application provides a method for detecting margins of a data signal. A receive end of a data signal may adjust a voltage of a reference power source; adjust, based on a plurality of reference moments included in a reference moment set, a moment of an edge of a data strobe signal transmitted by a transmit end of the data signal; and during the adjustment, for each reference voltage and each reference moment, determine whether a bit error exists in data obtained by decoding the data signal when the voltage of the reference power source is the reference voltage and the moment of the edge of the data strobe signal is the reference moment, to obtain a timing margin of the data signal at each reference voltage and a voltage margin of the data signal at each reference moment.

A biological identification safe deposit box includes a lock. The lock includes a first elastic lock catch, a first connecting rod, a second elastic lock catch, a second connecting rod, a transmission rotating disc, a driving motor, and a motor controller. A movable groove is defined in a center of the transmission rotating disc. A movable end of the driving motor extends into the movable groove. A driving block is disposed on a side surface of the movable end of the driving motor. A semi-annular adjusting groove, with respect to the driving block, is defined on an inner wall of the movable groove. An idle stroke exists when the driving block moves in the semi-annular adjusting groove. The lock further includes an emergency unlocking assembly. The emergency unlocking assembly drives the transmission rotating disc to rotate. The emergency unlocking assembly and the transmission rotating disc are separately disposed.

A controller for data strobe signal (DQS) position adjustment includes, when the controller obtains margin effective widths of all data signals in a transmission bus, it determines a left boundary and a right boundary based on the margin effective widths, where the left boundary is a largest value in minimum values of the margin effective widths of all the DQs, and the right boundary is a smallest value in maximum values of the corresponding margin effective widths when all the DQs are aligned with the left boundary. The controller calculates a first central position based on the left boundary and the right boundary, where the first central position is a center of a smallest margin effective width obtained after all the DQs are aligned during read data training, and adjusts a delay line (DL) of the DQS to the first central position.
