Abstract

In an embodiment, a first delayed persistence operation to store information in a log contained in a non-volatile memory (NVM) may be performed. The information may include, for example, a current value of a variable contained in the NVM. A second delayed persistence operation to store information in the variable may be performed. A third delayed persistence operation to store information in the NVM that indicates the log is cleared may be performed. A flush operation may be performed, for example after the first, second, and third delayed persistence operations. The flush operation may commit information associated with at least one of the first, second, or third delayed persistence operations to the NVM.

First claim

What is claimed is:

1. A method comprising:
performing a first delayed persistence operation to store information in a log contained in a non-volatile memory (NVM), the information including a current value of a variable contained in the NVM;
performing a second delayed persistence operation to store information in the variable;
performing a third delayed persistence operation to store information in the NVM that indicates the log is cleared; and
performing a flush operation…
