    摘要： A device includes non-volatile memory and a controller. The controller receives a write request including data and a logical address associated with a file. The controller stores the data at a data storage segment having a physical address and associates the physical address with the logical address and a file identifier for the file. The controller receives a second write request including data and the logical address associated with the file. The controller stores the data at a second data storage segment having a second physical address and associates the second physical address with the logical address and the file identifier. When a file delete request for the file is received, the controller identifies the first physical address and the second physical address using the file identifier and erases the information stored at the first data storage segment and the second data storage segment based upon the file identification.

    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.
