Embodiment Construction

[0068] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the device and method for using one-time programmable elements to achieve multiple programming according to the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments. Its specific implementation, structure, method, feature and effect thereof are described in detail as follows.

[0069] see figure 1 Shown is a diagram of a device for secondary programming using an OTP device according to an embodiment of the present invention. As shown in the figure, there is a selection device 120 connected to the first OTP element for adjustment 100 , the second OTP element for adjustment 102 , and the judging device 110 , wherein the judging device 110 is coupled to the second OTP element for adjustment 102 . In addition, a writing device 130 is further included, connected to the first adjust...

Abstract

The invention relates to an apparatus and method for using primary stylization unit to achieve multi-time stylization. The apparatus comprises: a choosing device, a first adjusting OTP unit, a second adjusting OTP unit and a quoting device. The quoting device outputs the choosing signal by weather the second adjusting OTP unit is stylization; the choosing device outputs one of the first OTP signal outputted by first adjusting OTP unit and the second OTP signal outputted by second adjusting OTP unit.

Description

technical field [0001] The present invention relates to an integrated circuit, in particular to a device and method for using one-time programmable elements to achieve multiple programming. Background technique [0002] In the manufacturing process of integrated circuits (IC), since the process parameters between machines cannot be completely consistent, and even the temperature in the same furnace tube cannot be evenly distributed, the same wafer (wafer) between each die (die) and die (die), so that between each wafer (wafer) and wafer (wafer), each batch of goods (lot) and goods ( lot), there will be different degrees of process parameter drift, so it will cause some parameter drift of the integrated circuit, for example: the frequency of the oscillator or the output voltage value of the voltage regulator (Voltage Regulator) will be different from the design There is an error in the value. If these analog circuit parameters drift too much, exceeding the specifications of...
