In one form, a non-volatile memory driver includes a function library defining a plurality of native function calls, and a hardware abstraction layer having an input coupled to and output of the function library for receiving the at least one instruction, and an output for providing a plurality of signals to cause a non-volatile memory to execute the at least one instruction. The non-volatile memory driver maintains the flash memory as a circular buffer using a bottom sector pointer and a next location pointer. In response to receiving a housekeeping command generated from corresponding command from an application layer as the selected native function call, the function library causes the hardware abstraction layer to selectively repack valid data of a bottom sector indicated by said bottom sector pointer using the next location pointer, and to selectively erase the bottom sector.
