Systems and methods for performing data recovery in a memory system
Abstract:
Systems and methods for performing data recovery are disclosed. A controller of a memory system may detect an error at a first page of memory and identify a data keep cache associated with the first page, the data keep cache associated with a primary XOR sum. The controller may further sense data stored at a second page and move the data to a first latch of the memory; sense data stored at a third page such that the data is present in a second latch of the memory; and calculate a restoration XOR sum based on the data of the second page and the data of the third page. The controller may further calculate the data of the first page based on the primary XOR sum and the restoration XOR sum, and restore the data of the first page.
