Abstract

The present disclosure includes apparatuses and methods for data replication. An example apparatus includes a plurality of sensing circuitries comprising respective sense amplifiers and compute components and a controller. The controller may be configured to cause replication of a data value stored in a first compute component such that the data value is propagated to a second compute component.

First claim

What is claimed is:

1. An apparatus, comprising:
a plurality of sensing circuitries each comprising a sense amplifier and a compute component; and
a controller configured to cause:
replication of a data value stored in a first compute component such that the data value is propagated to a second compute component; and
a data value received at the first respective compute component to be transferred to the second respective compute component in response to a determination that the first respective compute component has a replicate mask associated therewith.

2. The apparatus of claim 1 , wherein:
the first compute component is associated with a first sensing circuitry among the plurality of sensing circuitries;
the second compute component is associated with a second sensing circuitry among the plurality of sensing circuitries; and
the first compute component is in a same physical position with respect to the first sensing circuitry as the second compute component is with respect to the second sensing circuitry.

3. The apparatus of claim 1 , wherein:
the first compute component is associated with a first sensing circuitry among the plurality of sensing circuitries;
the second compute component is associated with a second sensing circuitry among the plurality of sensing circuitries; and
the first compute component is in a same logical position with respect to the first sensing circuitry as the second compute component is with respect to the second sensing circuitry.

4. The apparatus of claim 1 , wherein a storage location associated with the first compute component is coupled to a storage location associated with the second compute component.

5. The apparatus of claim 1 , wherein the controller is configured to cause the data value to be replicated in response to receiving a global control signal.

6. The apparatus of claim 1 , wherein k respective compute components are used to transfer a data word comprising k elements.

7. A method, comprising:
determining that a replicate mask associated with a second storage location is enabled;
generating a replicated data value; and
transferring the replicated data value from a first storage location to the second storage location based, at least in part, on a determination that a replicate mask associated with the second storage location is enabled.

8. The method of claim 7 , further comprising:
determining that a replicate mask associated with a third storage location is disabled; and
retaining a data value associated with the third storage location in response to the determination that the replicate mask associated with the third storage location is disabled.

9. The method of claim 7 , further comprising:
receiving the replicated data value at the second storage location; and
transferring the replicated data value from the second storage location to a different storage location based, at least in part, on the determination that the replicate mask associated with the second storage location is enabled.

10. The method of claim 7 , further comprising determining that a replicate mask associated with the first storage location is disabled, wherein the first storage location is a closest storage location having a disabled replicate mask to the second storage location.

11. The method of claim 7 , further comprising shifting data values stored in the first storage location and the second storage location in response to a determination that a data replication operation is complete.

12. An apparatus, comprising:
a plurality of sensing circuitries each comprising a sense amplifier and a compute component; and
a controller configured to cause:
replication of a data value stored in a first compute component such that the data value is propagated to a second compute component; and
a data value received at the first respective compute component to be retained at the first respective compute component in response to a determination that the first respective compute component does not have a replicate mask associated therewith.

13. An apparatus, comprising:
a plurality of sensing circuitries each comprising a sense amplifier and a compute component; and
a controller configured to cause:
replication of a data value stored in a first compute component such that the data value is propagated to a second compute component; and
a data value received at the first respective compute component to be transferred to the second respective compute component in response to a determination that the second respective compute component has a replicate mask associated therewith.
