Memory device with internal signal processing unit

A method, comprising:

• storing data in a plurality of analog memory cells;
• receiving a request from a memory controller to retrieve the stored data from the plurality of analog memory cells;
• retrieving storage values from the plurality of analog memory cells responsive to the received request;
• preprocessing the retrieved storage values to generate preprocessed data;
• and
• sending the preprocessed data to the memory controller;
• wherein preprocessing the retrieved storage values comprises determining a statistical property of the retrieved storage values, wherein the statistical property includes a Cumulative Distribution Function (CDF) of the retrieved storage values.

A computer-accessible non-transitory storage medium having program instructions stored therein that, in response to execution by a processor, cause the processor to perform operations comprising:

• storing data in one or more analog memory cells of a plurality of analog memory cells;
• receiving from a memory controller, a request to retrieve the stored data;
• receiving one or more analog control signals from the memory controller, wherein the analog control signals specify voltage or currents;
• reading storage values from the one or more analog memory cells of the plurality of analog memory cells dependent upon the received analog control signals;
• and
• sending the read storage values to the memory controller;
• wherein reading the storage values from the one or more analog memory cells of the plurality of analog memory cells comprises estimating a statistical property of the read storage values, wherein the statistical property includes a Cumulative Distribution Function (CDF) of the read storage values.
