Abstract

Systems and method relating generally to solid state memory, and more particularly to systems and methods for recovering data from a solid state memory. In one embodiment, the systems and methods include providing a flash memory circuit including a superset of memory cells, accessing a data set from a group of memory cells using a standard reference value to distinguish bit values in the group of memory cells, and based at least in part on determining that the group of memory cells was a last written group of memory cells, re-accessing a data set from the group of memory cells using a last written reference value to distinguish bit values in the group of memory cells.
