    摘要： A non-volatile random access memory (NVRAM) is used in a computer system to provide instant responses to sleep state transitions. The computer system includes a processor coupled to an NVRAM, which is accessible by the processor without passing through an I/O subsystem. The NVRAM is byte-rewritable and byte-erasable by the processor. In response to a request to enter a powered sleep state, the computer system converts the powered sleep state into a powered-off sleep state with system memory context stored in the NVRAM. The powered sleep state is defined as a state in which power is supplied to volatile random access memory in the computer system, and the powered-off sleep state is defined as a state in which power is removed from the volatile random access memory. In response to a wake event, the computer system resumes working state operations using the system memory context stored in the NVRAM.

    摘要翻译： 在计算机系统中使用非易失性随机存取存储器（NVRAM）来为睡眠状态转换提供即时响应。 计算机系统包括耦合到NVRAM的处理器，其可由处理器访问而不经过I / O子系统。 NVRAM是字节可重写的，可由处理器字节擦除。 响应于进入供电的睡眠状态的请求，计算机系统将动态睡眠状态转换为关闭休眠状态，并将系统存储器上下文存储在NVRAM中。 动力睡眠状态被定义为向计算机系统中的易失性随机存取存储器提供电力的状态，并且断电睡眠状态被定义为从易失性随机存取存储器去除电力的状态。 响应于唤醒事件，计算机系统使用存储在NVRAM中的系统存储器上下文来恢复工作状态操作。
