Abstract
The present disclosure includes apparatuses and methods for shift decisions. An example apparatus includes a memory device. The memory device includes an array of memory cells and sensing circuitry coupled to the array via a plurality of sense lines. The sensing circuitry includes a sense amplifier and a compute component coupled to a sense line and configured to implement logical operations and a decision component configured to implement a shift of data based on a determined functionality of a memory cell in the array.
Claims19
An apparatus, comprising:
- a memory device comprising sensing circuitry coupled to an array of memory cells via a plurality of sense lines;
- wherein the sensing circuitry includes:
- a sense amplifier coupled to a sense line;
- and
- decision circuitry configured to direct a shift in position of data responsive to an indicator of a determined functionality of a memory cell in the array;
- and
- shift circuitry configured to:
- in response to the indicator having a first value, cause a shift of a data value stored in a first memory cell to be stored in a second memory cell;
- and
- in response to the indicator having a second value, cause a shift of the data value stored in the first memory cell to be stored in a third memory cell, wherein the third memory cell is in a particular location with respect to the first memory cell.
An apparatus, comprising:
- a memory device comprising sensing circuitry coupled to an array of memory cells via a plurality of sense lines;
- wherein the sensing circuitry includes:
- a sense amplifier coupled to a sense line;
- and
- decision circuitry configured to direct a shift of data responsive to performance of a logical operation using an indicator value corresponding to a determined functionality of a memory cell in the array;
- and
- shift circuitry that couples the sense amplifier to at least a portion of the array, the shift circuitry configured to:
- in response to the indicator having a first value, cause a shift of a data value stored in a first memory cell to be stored in a second memory cell;
- and
- in response to the indicator having a second value, cause a shift of the data value stored in the first memory cell to be stored in a third memory cell, wherein the third memory cell is in a particular location with respect to the first memory cell.
A method for operating a memory device, comprising:
- accessing an indicator value that indicates a predetermined functionality of a memory cell;
- providing the indicator value to decision circuitry configured to direct a data shift based on the indicator value;
- deciding, in response to the predetermined functionality of the memory cell indicated by the indicator value, whether to shift data to either an adjacent block of a plurality of sense lines or to a non-adjacent block of a plurality of sense lines in the memory device;
- and
- shifting the data, using shift circuitry coupled to the memory cell, to either:
- an adjacent block of a plurality of sense lines in the memory device based on the decision by the decision circuitry in response to the indicator value being a first value;
- or
- a non-adjacent block of a plurality of sense lines in the memory device based on the decision by the decision circuitry in response to the indicator value being a second value, wherein the non-adjacent block is in a particular location with respect to the adjacent block.
