Abstract

In one embodiment, a method is provided that may include generating, at least in part by first circuitry comprised in an integrated circuit, check data based at least in part upon other data, and/or determining at least in part by the first circuitry, one or more locations of the check data and/or the other data in storage. The first circuitry may be capable of regenerating the other data based at least in part upon the check data. The method also may include issuing a request from second circuitry also comprised in the integrated circuit requesting that a wireless communication device transmit the other data, and/or receiving, by the second circuitry, a request issued from the wireless device, to retrieve the other data. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.
