To gauge the "freshness" of the data, you might decide to add a timestamp field to the object so that you could easily detect whether the object and the backing store were out of sync.
所有字节宽度的存储器都有标准SRAM脚位输出，他们操作方式跟SRAM一样，并且提供非易失性存储，无需后备电池。
All byte wide memories have standard SRAM pinouts. they operate like SRAMs and provide nonvolatile storage with no requirement for battery backup.
