| 1. A method for storing transient state information, the method comprising:
defining a first logical storage space within at least one storage device, wherein the first logical storage space is defined
according to at least one characteristic of a first logical memory space in a volatile storage medium utilized for storing
transient state information of a processing system;
copying transient state information from a first logical location within the first logical memory space to a second logical
location within the first logical storage space;
determining at predetermined time intervals whether the transient state information stored at the first location within the
first logical memory space has changed; and
moving the transient state information stored at the second logical location within the first logical storage space to a second
logical storage space, in response to determining that the transient information stored at the first logical location within
the first logical memory space has changed,
wherein there is a one-to-one mapping between the first logical memory space and the first logical storage space.
