Abstract: A link balance adjustment method includes the following steps. A connection port initiates a balance adjustment process through an interrupt signal. A microprocessor provides an adjustment parameter for an external device from a register and transmits the adjustment parameter to the connection port. A measurement signal is initiated by the microprocessor, and the measurement signal enables the connection port to measure the signal quality after the adjustment parameter has been applied by the external device. The microprocessor determines whether the connection port needs to perform a preprocessing. When the microprocessor determines that the connection port needs to perform a preprocessing, the connection port performs the preprocessing and generates preprocessing data. The connection port transmits the preprocessing data to the register. The microprocessor reads the preprocessing data or the signal quality in the register.

Abstract: A method for manufacturing a flash memory device includes providing a substrate structure including a substrate, an insulating layer on the substrate, and a stack structure including a charge storage layer, a tunneling dielectric layer, a charge trapping layer, a blocking dielectric layer and a gate layer disposed sequentially from bottom to top on the insulating layer. The method also includes performing a selective nitriding process on the substrate structure to form a nitride layer exposed surfaces of the charge storage layer and the gate layer, and forming an isolation region on side surfaces of the stack structure. The method can mitigate the problem of an undesirable increase in the threshold voltage with an increase in the integration density of the flash memory device.
