Abstract
The invention provides a reading circuit for stored data of an electrically programmable fuse wire, and an electronic apparatus. The reading circuit for the stored data of the electrically programmable fuse wire comprises a pulse signal module, an amplifier module and a trigger module, wherein the pulse signal module is connected to the electrically programmable fuse wire and controls switch-on of the electrically programmable fuse wire by utilizing a pulse signal during a reading cycle of the stored data of the electrically programmable fuse wire; the amplifier module is connected to the pulse signal module and amplifies an output signal of the pulse signal module; and the trigger module is connected to the amplifier module to sample an output signal of the amplifier module, and outputs the sampled signal under the control of a clock signal. According to the reading circuit, the time for enabling a current to flow through the electrically programmable fuse wire can be greatly shortened, and the misreading probability caused by soft electro migration is reduced, so that the performance of the electrically programmable fuse wire in HTOL testing is improved.
Description
technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a reading circuit and an electronic device for storing data in an electric programmable fuse. Background technique [0002] Integrated circuit semiconductor devices may include a large number of electrically programmable fuses (eFuses), which can be used for non-volatile memory. The eFuses can be electrically programmed (ie, fused) individually within the integrated circuit. The eFuse technology emerged on the basis of the original integrated circuit technology. It has many advantages. It can not only implement redundancy, thereby achieving a high yield of the chip, but also enable the chip to be automatically programmed to be more automated and intelligent. [0003] Nowadays, the theory and technology of electric programmable fuses are gradually mature, and the scope of application continues to expand, so higher requirements are put forward for its stability and rea...
