ABSTRACT:
A non-volatile memory device stores configuration variables for use by a computer firmware. The variable is initially stored in the memory device in a manner that minimizes the number of bits used to store the variable that are in the updated state. When a request is received to change the initial value of the variable to an updated value, the value is changed in place by changing only the bits used to store the variable from an erased state to an updated state, by only setting the invert flag, by setting the invert flag and by changing one or more of the bits of the variable from the erased state to the updated state, or by storing the updated value of the variable in a new location in the memory device.
