  • Patent number: 11971498
    Abstract: Hybrid positioning methods and electronic apparatuses are provided. A representative method includes: obtaining initial location information; computing initial moving information based upon the sensor readings; computing estimated location information based on the initial moving information and the initial location information; acquiring geographical location readings if a location update condition is satisfied; generating reference location information based on the geographical location readings acquired; comparing the estimated location information with the reference location information to obtain a deviation information; computing a calibrated moving information based on the estimated location information and the deviation information; and computing a calibrated location information based on the deviation information, calibrated moving information and the estimated location information.

  • Patent number: 11947818
    Abstract: The present invention provides a method for accessing a flash memory module, wherein the method includes the steps of: writing data into a plurality of pages of a specific block, and establishes or updates a F2H mapping table based on physical addresses of the plurality of pages and logical addresses of the data; using the F2H mapping table to update a H2F mapping table; initializing a flush-bitmap, wherein the flush-bitmap records a plurality of flush bits corresponding to the physical addresses of the plurality of pages, respectively; receiving a trim command from a host device, wherein the trim command asks to mark at least one of the logical addresses of the data as invalid; updating the H2F mapping data according to the trim command; updating the flush-bitmap according to the trim command; and writing the updated H2F mapping table and the updated flush-bitmap into the flash memory module.

  • Patent number: 11940828
    Abstract: A voltage tracking circuit is provided. The voltage tracking circuit includes first and second P-type transistors and a control circuit. The drain of the first P-type transistor is coupled to a first voltage terminal. The gate and the drain of the second P-type transistor are respectively coupled to the first voltage terminal and a second voltage terminal. The control circuit is coupled to the first and second voltage terminals and generates a control voltage according to the first voltage and the second voltage. The sources of the first and second P-type transistors are coupled to an output terminal of the voltage tracking circuit, and the output voltage is generated at the output terminal. In response to the second voltage being higher than the first voltage, the control circuit generates the control signal to turn off the first P-type transistor.

  • Patent number: 8817521
    Abstract: A control method for at least one memory cell is disclosed. The memory cell includes a transistor and a resistor. The resistor is connected to the transistor in series between a first node and a second node. In a programming mode, the memory cell is programmed. When it is determined that the memory cell has been successfully programmed, impedance of the memory cell is in a first state. When it is determined that the memory cell has not been successfully programmed, a specific action is executed to reset the memory cell. The impedance of the memory cell is in a second state after the step resetting the memory cell. The impedance of the memory cell in the second state is higher than that of the memory cell in the first state.

  • Patent number: 8223528
    Abstract: A control method for at least one memory cell is disclosed. The memory cell includes a transistor and a resistor. The resistor is connected to the transistor between a first node and a second node. In a programming mode, the memory cell is programmed. The step of programming the memory cell includes providing a first controlling voltage to a gate of the transistor, providing a first setting voltage to the first node, and providing a second setting voltage to the second node. When it is determined that the memory cell has been successfully programmed, a specific action is executed.
