Abstract

A system including a write module to write pilot data at predetermined locations in a page of memory cells that are interspersed with user data in the page. The pilot data has a first predetermined pattern and provides an indication of a disturbance experienced by the user data due to noise and a read, write, or erase operation performed on the page. A read module reads data from the predetermined locations subsequent to writing the pilot data. A signal processing module compares the data read from the predetermined locations with the pilot data and estimates, based on the comparison of the data read from the predetermined locations in the page with the pilot data, and the first predetermined pattern of the pilot data, the disturbance experienced by the user data due to the noise and the read, write, or erase operation performed on the page.
