Methods and systems for an analog CAM with fuzzy search

An analog content addressable memory (CAM) cell, comprising:

• a memristor storing an analog value associated with data stored in the analog CAM cell;
• a plurality of transistors;
• a data line receiving an applied voltage (VDL) encoding input data for searching the data stored in the analog CAM cell;
• and
• a plurality of search-variance parameter lines vertically aligned and coupled to a transistor of the plurality of transistors, the plurality of search-variance parameter lines comprising transistor source lines to determine a variance range from the stored data to match the input data.

An analog content addressable memory (CAM) cell, comprising:

• a plurality of memristors storing a plurality of analog values to set one or more limits for a stored search range associated with data stored in the analog CAM cell;
• a first data line receiving a high voltage that is associated with input data for searching the data stored in the analog CAM cell including a high limit for a variance range to match the input data to the data stored in the analog CAM cell;
• and
• a second data line receiving a low voltage that is associated with the input data for searching the data stored in the analog CAM cell including a low limit for the variance range to match the input data to the data stored in the analog CAM cell.
