Abstract
Various systems and methods to use a plurality of linked lists for keeping track of changes to be made in data sets currently in a flash memory. To enhance efficiency of the system, the changes to be made in any particular data set are aggregated in a random access memory (“RAM”) until a sufficient volume of changes have been aggregated to justify a rewrite of the flash memory block in which the particular data set is stored. Since a flash memory may have millions of memory blocks and data sets, there are potentially tremendous demands on the memory resources of the RAM to keep track of all the changes, but the problem presented by these potential demands is avoided through the use of linked lists, in which each list links all of the changes that have been aggregated in RAM and that apply to one specific data set.
