Patent attributes
The present disclosure includes apparatuses and methods for material implication operations in memory with reduced program voltages. An example apparatus can include an array of memory cells that further includes a first memory cell coupled to a first access line and to a first one of a plurality of second access lines and a second memory cell coupled to the first access line and to a second one of the plurality of second access lines. The circuitry can be configured to apply, across the second memory cell, a first voltage differential having a first polarity and a first magnitude. The first voltage differential reduces, if the second memory cell is programmed to a first data state, a magnitude of a drifted threshold voltage for programming the second memory cell to a second data state. The circuitry is further configured to apply, subsequent to the application of the first voltage differential, a first signal to the first access line. The circuitry is further configured to, while the first signal is being applied to the first access line, apply, subsequent to the application of the first voltage differential, a second voltage differential having a second polarity and the first magnitude across the first memory cell and apply a third voltage differential having the second polarity across the second memory cell. A material implication operation is performed as a result of the first, second, and third voltage differentials applied across the first and the second memory cells with a result of the material implication operation being stored on the second memory cell.
