摘要:
An apparatus is described that is configured to modify a signal to at least substantially remove a noise portion from the signal. In one or more implementations, the apparatus is a collaborative filtering module that is configured to communicatively couple to a memory array having a plurality of memory cell blocks. The memory array is configured to furnish a signal representative of data stored within the plurality of memory cell blocks. The collaborative filtering module is configured to determine a noise distribution associated with the plurality of memory cell blocks and generate a noise prediction, which is based upon the noise distribution, when a read operation for the plurality of memory cell blocks is issued. The collaborative filtering module is also configured to modify the signal utilizing the noise prediction to at least substantially remove noise from the signal.
