Claim 0:
1. A memory device, comprising:
an array of memory cells; and
control circuitry configured to cause the memory device to:
compare input data to data stored in a plurality of memory cells of the array of memory cells connected to a data line, wherein the input data comprises a plurality of digits, wherein each digit of the input data corresponds to a respective pair of series-connected memory cells of the plurality of memory cells connected in series with a respective resistor of a plurality of resistors, and wherein a resistance value of one resistor of the plurality of resistors is different than a respective resistance value of each remaining resistor of the plurality of resistors;
in response to a mismatch between one digit of the input data and the data stored in the respective pair of series-connected memory cells for the one digit of the input data, cause a first level of current to flow from the data line through the respective pair of series-connected memory cells for the one digit of the input data;
in response to a mismatch between a different digit of the input data and the data stored in the respective pair of series-connected memory cells for the different digit of the input data, cause a second level of current, different than the first level of current, to flow from the data line through the respective pair of series-connected memory cells for the different digit of the input data;
compare a representation of a level of current in the data line to a reference;
deem the input data to potentially match the data stored in the plurality of memory cells in response to the representation of the level of current in the data line being less than the reference; and
deem the input data to not match the data stored in the plurality of memory cells in response to the representation of the level of current in the data line being greater than the reference.
