Memory device with internal signal processing unit

A method for operating a memory, wherein the memory includes a plurality of pages cells, and wherein each page of the plurality of pages includes a plurality of memory cells, the method comprising:

• receiving, by the memory, a read request from a controller to read a first page of the plurality of pages;
• reading a first set of storage values from the first page of the plurality of pages in response to the read request;
• storing the first set of storage values in a buffer;
• receiving, by the memory, an interference cancellation request from the controller;
• reading at least one potentially-interfering page of the plurality of pages in response to the interference cancellation request to generate interference results;
• reading a set of cross-coupling coefficients from a lookup table (LUT), wherein each cross-coupling coefficient specifies an interference level from at least one neighboring cell to a target cell included in the first page of the plurality of pages;
• iteratively performing a plurality of read operations on the first page of the plurality of pages to generate a respective plurality of read results, wherein each read operation of the plurality of read operations uses a respective read threshold of a plurality of shifted read thresholds;
• and
• retrieving, for a first read result of the respective plurality of read results, a decision to retain results of a second read result of the respective plurality of read results from the LUT dependent upon at least the first read result and the second read result.

A system, comprising:

• a memory device including a plurality of pages;
• a controller configured to send a read request to read a first page of the plurality of pages to the memory device;
• wherein the memory device is configured to:
• read a first set of storage values from the first page of the plurality of pages in response to the read request;
• store the first set of storage values in a first buffer;
• receive an interference cancellation request from the controller;
• read at least one potentially-interfering page of the plurality of pages in response to the interference cancellation request to generate interference results;
• read a set of cross-coupling coefficients from a lookup table (LUT), wherein each cross-coupling coefficient specifies an interference level from at least one neighboring cell to a target cell included in the first page of the plurality of pages;
• iteratively perform a plurality of read operations on the first page of the plurality of pages to generate a respective plurality of read results, wherein each read operation of the plurality of read operations uses a respective read threshold of a plurality of shifted read thresholds;
• and
• retrieve, for a first read result of the respective plurality of read results, a decision to retain results of a second read result of the respective plurality of read results from the LUT dependent upon at least the first read result and the second read result.
