Abstract

The present disclosure includes apparatuses and methods related to a shift skip. An example apparatus comprises a plurality of sensing circuitries, comprising respective sense amplifiers and respective compute components. A controller is configured to, responsive to a mask data unit associated with a first sensing circuitry having a particular value, cause a data value to be shifted from a second sensing circuitry to a third sensing circuitry without shifting the data value to the first sensing circuitry, wherein the first sensing circuitry is physically located between the second sensing circuitry and the third sensing circuitry.

Claims (30)

1. An apparatus, comprising:

a plurality of sensing components comprising respective sense amplifiers and respective compute components; and

a controller configured to cause a mask data unit to be stored in a first sensing component among the plurality of sensing components.

2. The apparatus of claim 1 , wherein the controller is further configured to cause the mask data unit to be stored in the first sensing component based, at least in part, on application of a shift skip mask signal to a column repair signal line coupled to the first sensing component.

3. The apparatus of claim 1 , wherein the controller is further configured to cause a data value to be shifted from a second sensing component coupled to the first sensing component to a third sensing component coupled to the first sensing component without shifting the data value to the first sensing component.

4. The apparatus of claim 3 , wherein the first sensing component is disposed between the second sensing component and the third sensing component.

5. The apparatus of claim 1 , wherein the controller is further configured to cause a mask data bit corresponding to a state of a fuse coupled to the first sensing component to be stored in the first sensing component based, at least in part, on application of a shift skip mask signal to a column repair signal line coupled to the first sensing component.

6. The apparatus of claim 1 , wherein the controller is further configured to cause the mask data unit to be stored in the first sensing component without transferring data to circuitry external to the plurality of sensing components.

7. An apparatus, comprising:

a plurality of sensing components, each sensing component including a sense amplifier and a compute component;

a controller coupled to the sensing components, wherein the controller is configured to:

alter an amount of time associated with a shift cycle in response to a determination that at least one sensing component among the plurality of sensing components has a particular mask data value associated therewith.

8. The apparatus of claim 7 , wherein the controller is further configured to alter the amount of time associated with the shift cycle without transferring data to circuitry external to the plurality of sensing components.

9. The apparatus of claim 7 , wherein the controller is further configured to shift a data value from a first sensing component to a second sensing component without shifting the data to at least one sensing component disposed between the first sensing component and the second sensing component in response to detection of the particular mask data value being stored in the at least one sensing component.

10. The apparatus of claim 9 , wherein the controller is further configured to drive a first signal associated with a first pair of signal lines low while driving a second signal associated with a second pair of signal lines high as part of an operation to cause a data value to be shifted from the first sensing component to the second sensing component.

11. The apparatus of claim 10 , wherein the first pair of signal lines are a pair of inverse column repair signal lines and the second pair of signal lines are a pair of column repair signal lines.

12. The apparatus of claim 7 , wherein the particular mask data value corresponds to an indication that a data value is not to be shifted to the sensing component storing the particular mask data value.

13. The apparatus of claim 7 , wherein the particular mask data value is based on a state of a fuse coupled to at least one sensing component among the plurality of sensing components.

14. A system, comprising:

a host; and

a memory device coupled to the host and configured to, responsive to an instruction received from the host, cause a data value to be shifted from a first sensing component to a second sensing component without shifting the data value to a third sensing component disposed between the first sensing component and the second sensing component.

15. The system of claim 14 , wherein the memory device further comprises a plurality of sensing components comprising respective sense amplifiers and respective compute components.

16. The system of claim 14 , wherein the memory device is further configured to cause a mask data unit to be stored in the third sensing component based, at least in part, on application of a shift skip mask signal to a column repair signal line coupled to the third sensing component.

17. The system of claim 14 , wherein the memory device is further configured to determine that a mask data unit is stored in the third sensing component.

assert a first signal on a first pair of column repair signal lines corresponding to the third sensing component;

deassert the first signal in response to a determination that a shift skip mask data unit is stored in the third sensing component; and

assert a second signal on a second pair of column repair signal lines corresponding to the second sensing component in response to deassertion of the first signal.
