  • Publication number: 20240096411
    Abstract: A method for performing memory access of a Flash cell of a Flash memory includes: performing a series of sensing operations respectively corresponding to a plurality of sensing voltages, wherein a sensing voltage of a specific sensing operation of the series of sensing operations has a sensing voltage determined according to a result of an initial sensing operation of the series of sensing operations; determining a threshold voltage of the Flash cell according to at least a digital value generated by the series of sensing operations; and using the determined threshold voltage to perform soft decoding of the Flash cell.

  • Patent number: 10792767
    Abstract: A laser preheating control method is applied to a laser preheating control device. When a cutter processes a workpiece along a process path, a laser source of the device is provided to output a laser beam to the workpiece for selectively forming a laser spot on the workpiece surface. And according to a movement direction of the cutter, a laser controller of the device is provided to form the laser spot only on a preheating region of the workpiece, where in front of the cutter in the process path, for preheating the workpiece in the preheating region. As a result, the laser spot will not repeatedly heat the workpiece behind the cutter in the process path, and the qualitative change of the workpiece caused by repeating heating is preventable.
