INTER-CELL INTERFERENCE ESTIMATION BASED ON A PATTERN DEPENDENT HISTOGRAM

摘要

An apparatus comprising a memory and a controller. The memory may be configured to process a plurality of read/program operations. The memory may comprise a plurality of memory units each having a size less than a total size of the memory. The controller may be configured to perform a plurality of reads on a victim cell. The controller may be configured to store measured victim information from the plurality of reads on the victim cell. The controller may be configured to perform one or more reads on a plurality of aggressor cells. The controller may be configured to store measured aggressor information from the one or more reads on the plurality of aggressor cells. The controller may be configured to generate inter-cell interference parameters based on the measured victim information and the measured aggressor information. The controller may be configured to mitigate inter-cell interference based on the inter-cell interference parameters.

1. An apparatus comprising:
a memory configured to process a plurality of read/program operations, said memory comprising a plurality of memory units each having a size less than a total size of said memory; and a controller configured to (i) perform a plurality of reads on a victim cell, (ii) store measured victim information from said plurality of reads on said victim cell, (iii) perform one or more reads on a plurality of aggressor cells, (iv) store measured aggressor information from said one or more reads on said plurality of aggressor cells, (v) generate inter-cell interference parameters based on said measured victim information and said measured aggressor information, and (vi) mitigate inter-cell interference based on said inter-cell interference parameters.
