半导体供应商(包括内存供应商)正在提供增强的支持，以帮助汽车Tier 1和原始设备制造商在功能安全方面做出努力. In November, 微米 released a video, “Questions to Ask Your 内存 Supplier 沙巴体育安卓版下载 Functional Safety for DRAM在这篇文章中，我们概述了记忆在影响整体安全水平方面发挥的日益重要的作用，以及在制定安全策略时需要考虑的问题.
\r\nISO 26262将功能安全定义为“不存在由于电气/电子系统故障行为引起的危害而造成的不合理风险”.” Malfunctions are classified into two failure types:
\r\n- \r\n
- 系统故障:这些故障以确定的方式发生-通常在沙巴体育结算平台设计或开发期间引入. 这些失败通常通过采用文档化良好的过程和方法来解决, including safety planning, safety concept documentation, requirements traceability, proactive safety analysis tools, 健壮的验证, operational procedures and other associated factors. \r\n
- 随机故障:这些故障是在设备的生命周期中任意出现的故障. 随机故障可以进一步分为两类:瞬态故障(单事件异常或软错误)或永久故障(硬错误，如卡在逻辑级别). 这些类型的故障通常通过引入有助于识别这些故障的安全机制来解决, enabling the system to take the proper actions, including correcting the fault or enabling the system to maintain a safe state.
\r\n \r\n
Several safety mechanisms are employed at the hardware and system levels:
\r\n
- \r\n
- Redundancy: This mechanism can typically be implemented at the hardware level. \r\n
- Cyclic redundancy check: This mechanism is typically used for error detection. \r\n
- 纠错码:该机制通常用于错误检测和纠错. \r\n
- 内置自检:该机制提供额外的电路，以验证准确的设备操作, either continuously or during 权力-up. \r\n
用于检测随机故障及时(FIT)和风险可能性的安全机制的有效性通过各种度量来衡量, including single-point fault metric (SPFM) and latent fault metric (线性调频). 这些指标用于度量给定硬件组件的功能安全性.
\r\nASILs establish safety requirements for automotive components
\r\nASIL refers to the 汽车 Safety Integrity Level, 由ISO 26262标准定义的用于道路车辆功能安全的风险分类系统. ASIL A systems have the least stringent level of safety reduction, whereas ASIL D is the most stringent. Because higher ASIL levels typically imply increased levels of cost and complexity, 给定系统所需的ASIL级别与该系统故障对车辆运行的影响直接相关.
\r\n硬件系统, ASIL需求确定了故障度量的必要值，如下表所示.
\r\n| ASIL | \r\n失败率(适合 | \r\n线性调频 | \r\nSPFM | \r\n

| C | \r\n< 100 | \r\n≥ 80% | \r\n≥ 97% | \r\n
| D | \r\n< 10 | \r\n≥ 90% | \r\n≥ 99% | \r\n
