Abstract
The present disclosure includes apparatuses and methods related to performing logical operations using sensing circuitry. An example apparatus comprises an array of memory cells and sensing circuitry coupled to the array. The sensing circuitry is configured to perform a logical operation using a data value stored in a first memory cell coupled to a sense line as a first input and a data value stored in a second memory cell coupled to the sense line as a second input. The sensing circuitry is configured to perform the logical operation without transferring data via a sense line address access.
Claims20
A system, comprising:
- a memory device;
- a host coupled to the memory device and configured to provide an instruction to the memory device to perform a logical operation using sensing circuitry comprising a sense amplifier and a compute component coupled to a column of an array of memory cells;
- and
- wherein the memory device is configured to provide control signals to the sensing circuitry to perform the logical operation by using a first data value on a sense line corresponding to the column at a first point in time as a first input and a second data value on the sense line at a second point in time as a second input.
A method of operating a system, the method comprising:
- providing an instruction to a memory device;
- and
- executing, on the memory device, the instruction to perform a logical operation using sensing circuitry comprising a sense amplifier and a compute component coupled to a column of an array of memory cells;
- and
- wherein performing the logical operation comprises providing control signals to the sensing circuitry to perform the logical operation by using a first data value on a sense line corresponding to the column at a first point in time as a first input and a second data value on the sense line at a second point in time as a second input.
A system, comprising:
- sensing circuitry comprising:
- a sense amplifier coupled to a pair of complementary sense lines of an array of memory cells;
- a compute component comprising a latch configured to serve as an accumulator and coupled to the sense amplifier via a pair of pass transistors;
- and
- a controller configured to provide signals to the sensing circuitry in association with performing a compute function that comprises performing a logical operation on a data value represented by a signal on at least one of the pair of complementary sense lines.
