Technically an integrated circuit, an eFuse provides overcurrent, overvoltage, overtemperature, and inrush current protection to circuits and electronic components. An eFuse also has current-limiting characteristics and can transmit diagnostic data to automatic switches and users in real time. Thermal ...
为了提高良率,多年来冗余电路 (Redundancy Circuit)都被大家习惯来使用。与之相对应,需要在结构的最上 层制作一些熔丝结构,其作用在于当芯片完成时,若其中有部分存储单元、字 线或者导线的功能有问题时,就可以利用熔丝跳接另一些冗余(redundant cells)的存储单元、字线或者导线来取代。这样,通过增加相应的逻辑控制电...
在一些实施例中,处理器可以包括一个或多个处理核(例如,单核处理器(s)或多核处理器(s))。仅作为举例,处理器可以包括中央处理单元(centralprocessingunit,cpu)、专用集成电路(applicationspecificintegratedcircuit,asic)、专用指令集处理器(applicationspecificinstruction-setprocessor,asip)、图形处理单元(graphicsprocessingun...
本发明实施例公开了一种eFUSE烧录方法、装置和电子设备及存储介质,本发明提供的技术方案通过使用预置于嵌入式设备中的引导程序对其主控芯片上的eFUSE进行烧录,由于引导程序在主控芯片上电或复位后自动启动,使得eFUSE烧录在引导程序启动过程中可以根据系统配置选择自动完成或者手动完成,烧录过程简单、清晰并且不易出错,从而简...
所述处理器可以由集成电路(integrated circuit,IC) 组成,例如可以由单颗封装的IC 所组成,也可以由连接多颗相同功能或不同功能的封装IC而组成。举例来说,处理器301可以仅包括中央处理器(centralprocessing unit,CPU)。在本申请实施方式中,CPU可以是单运算核心,也可以包括多运算核心。 存储器302,用于存储处理器301的...

An exemplary embodiment of an efuse device is provided, operating in a write mode and a read mode and comprising a source line, a cell, a blow device, and a sensing circuit. The cell has a first terminal coupled to the source line and a second terminal. The blow device is coupled ...
Fig. 1 - Short Circuit Protection while Pre-Charging In Fig. 1, the output of the eFuse is shorted. The output voltage VOUT increases marginally after the system is enabled so the logic signal V_OUT_ < 10 % stays high for the entire 25 ms period, and therefore, the pre-charge is ...
The automotive eFuse design is segmented into distinct subsections. Firstly, there’s the Current Sense and Activation (CSA) component. The CSA circuit holds significant prominence within the eFuse system design, maintaining a consistency of 90% across its structure. This stability allows it to be...
